Answer:
The definition of "perfect square" is: "A perfect square is a number that can be expressed as the product of an integer by itself or as the second exponent of an integer." For example, 16 would be a perfect square because [tex]4^{2}[/tex] would equal 16. But 12 is not a perfect square because no number could multiply by itself to get 12. I hope this helps you! :)

whats the solution of 4-|x| = 1
Answer:
Well, x=3, -3
Step-by-step explanation:
If you use a calculator you'll easily be able to figure this out.
Answer:
x = -3 or x = 3
Step-by-step explanation:
4 - |x| = 1
Subtract 4 from both sides:
4 - 4 - |x| = 1 - 4
- |x| = -3
Divide both sides by -1:
[tex]\frac{-|x|}{-1} = \frac{-3}{-1}[/tex]
x = -3 or x = 3

answer these 3 questoins
Answer:
b) m = 1/2
c) m = 3
d) m = 1/3
Step-by-step explanation:
b) rise = 1, run = 2; m = rise/run, so m = 1/2
c) rise = 3, run = 1; m = rise/run, so m = 3
d) rise = 1, run = 3; m = rise/run, so m = 1/3

I need help with this question
Answer:
There are no solutions.
Step-by-step explanation:
3(n+1) = 3n+3.
3n+3-5 = 3n-2.
3n-2 doesn't equal 3n-1, so there are no solutions.

which addition matches the problem...
Answer:
The addition that matches the problem is the first one.
Step-by-step explanation:
The red line goes back 8 so it is a -8 and the blue line goes forward 4 so it is a postive 4.

Jaylo bought a television priced at $349. She received a 20% discount and paid a 7% sales tax. What is the total price of the television? A. $74.69 B. $298.74 C. $348.87 D. $448.12
Answer:
B
Step-by-step explanation:
349 ---100%
x ------ 20%
x= (349×20)÷100
x=69.8
349-69.8=279.2
279.2 ---100%
x-----7%
x=(279.2×7)÷100
x=19.54
Final result
279.2+19.54=298.74
And final result is B
The total price of the television is B. $297.74
Given that,
Jaylo bought a television priced at $349. She received a 20% discount and paid a 7% sales tax.Based on the above information, the calculation is as follows:
[tex]= (\$349 \times (1- 0.20) + \$349 \times (1- 0.20) \times 0.07)\\\\= \$279.20 + \$19.544[/tex]
= $297.74

How do I solve (a+b)(3a-b)(2a+7b)
Please help
Answer:
Simplifying
-5 + -1(3a + b) + (2a + -7b) = 0
-5 + (3a * -1 + b * -1) + (2a + -7b) = 0
-5 + (-3a + -1b) + (2a + -7b) = 0
Remove parenthesis around (2a + -7b)
-5 + -3a + -1b + 2a + -7b = 0
Reorder the terms:
-5 + -3a + 2a + -1b + -7b = 0
Combine like terms: -3a + 2a = -1a
-5 + -1a + -1b + -7b = 0
Combine like terms: -1b + -7b = -8b
-5 + -1a + -8b = 0
Solving
-5 + -1a + -8b = 0
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '5' to each side of the equation.
-5 + -1a + 5 + -8b = 0 + 5
Reorder the terms:
-5 + 5 + -1a + -8b = 0 + 5
Combine like terms: -5 + 5 = 0
0 + -1a + -8b = 0 + 5
-1a + -8b = 0 + 5
Combine like terms: 0 + 5 = 5
-1a + -8b = 5
Add '8b' to each side of the equation.
-1a + -8b + 8b = 5 + 8b
Combine like terms: -8b + 8b = 0
-1a + 0 = 5 + 8b
-1a = 5 + 8b
Divide each side by '-1'.
a = -5 + -8b
Simplifying
a = -5 + -8b

40 percent of the leaves are still green. If there are 12,000 total leaves, how many are no longer green?
Answer: 7200
Step-by-step explanation:
40 percent of leaves are green so 60 percent of leaves are no longer green.
there are 12000 total leaves so [tex]\frac{60}{100}[/tex] × [tex]12000[/tex] = 7200

Question 8 measurements. Angle H (acute) Angle M (obtuse) Angle K (acute)
Question 9 measurements. Angle P (right) Angle Q (obtuse) Angle R (acute) Angle S (obtuse) Angle T (right)
Any angle that is visibly smaller than 90° in shape is an acute angle.
Any angle that has a square denoted inside the angle means that it is a 90° angle, therefore implying that it is a right angle.
Any angle that is visibly bigger than 90° in shape is an obtuse angle.
Note that in the Q.8, the total summation of the interior angles for a triangle is 180°. In this case, ∠H & ∠K can be safely assumed to be smaller than right angles, which means that ∠M would be either a right angle or obtuse. However, it is not given that ∠M is a right angle, and so the answer is obtuse.
a. Angle H: acute angle
b. Angle M: obtuse angle
c. Angle K: acute angle
It is given that angles P & T are right angles (as denoted by the squares). Therefore, angle Q & S are obtuse, and angle R is acute, based on visible differences:
a. angle P: Right angle.
b. angle Q: Obtuse angle.
c. angle R: Acute angle.
d. angle S: Obtuse angle.
e. angle T: Right angle.
Usually you will not be using visibility to solve the angle measurements, but in this case, it is not stated that shapes are not drawn to scale. Therefore, you can safely assume based on what the angles look like to answer.

explain how you got the answer because I somehow got x > -5 as my answer, please and thanks.
Answer: x>-5
Step-by-step explanation:
-5(x+7)<-10
Distribute the -5.
-5x-35<-10
Add 35 to both sides.
-5x<25
Divide both sides by -5.
x>-5
Answer:
x > - 5
Step-by-step explanation:
-5(x+7)< -10
-5x - 35 < - 10
- 5x < - 10 + 35
x > 25/-5
which fact helps you prove the isosceles triangle theorem, which states that the base angles of any isosceles triangle have equal measure?

One-fourth of a number is five-eights. Find the number. Simplify your answer
Answer:
2.50 or 2.5
Step-by-step explanation:
1/4=.25 so 25% of a number=5/8=0.625
So we multiply .625*4 to get the number. Since it's 25% and we want 100% to get it back to the original number
.625*4=2.50 or 2.5

Solve the given equation.
- 29 = - 13 - n
Write step by step how you solved it.
Answer:
The answer is n=16
Step-by-step explanation:
Let's solve your equation step-by-step.
−29=−13−n
Step 1: Simplify both sides of the equation.
−29=−13−n
−29=−13+−n
−29=−n−13
Step 2: Flip the equation.
−n−13=−29
Step 3: Add 13 to both sides.
−n−13+13=−29+13
−n=−16
Step 4: Divide both sides by -1.
−n/−1 =−16/−1
n=16
