so x=2 right there for

(-3)2+6=(2)-24

-6+6=4-24

0=20

Answer:

Option B, [tex]x =[/tex] ± [tex]9.49[/tex]

Step-by-step explanation:

Step 1:  Add 90 to both sides

[tex]x^2 - 90 = 0[/tex]

[tex]x^2 - 90 + 90 = 0 + 90[/tex]

[tex]x^2 = 90[/tex]

Step 2:  Square root both sides

[tex]\sqrt{x^2} = \sqrt{90}[/tex]

[tex]x =[/tex] ± [tex]9.49[/tex]

Answer: Option B, [tex]x =[/tex] ± [tex]9.49[/tex]

Hi!

We are asked to find the ratio.

A ratio is a relationship/comparison between two or more numbers based on their numerical value.

We know that, for every 2 triangles there are 6 circles. We can set up our ratio to look like this:

[tex]\cfrac{2}{6}[/tex]

---

(NOTE: there are many different ways to write ratios, including: "x:y", "x to y", or "x/y")

---

The question asks us to write it in simplest form. The fraction [tex]\cfrac{2}{6}[/tex] is NOT in simplest form. It can be simplified to:

[tex]\cfrac{1}{3}[/tex]

This is the ratio in simplest form.

y = -x/5 - 3

Step-by-step explanation:

Slope intercept form: y = mx + b

5y = -15 - x

y = -15/5 -x/5

y = -x/5 - 3

Answer:

-7240

Step-by-step explanation:

The nth term is -10n + 24.

So the combination of the first and second term would be (-10+24)+(-10x2+24) and this would continue for the first 40 terms so the 24s would add up to 24x40=960. Meanwhile, the -10s would keep adding up so it would be -10-20-30-40.... which you can simplify by making it -10(1+2+3+4) all the way to 40 to make the calculation easier... u can further simplify by making 41 = one pair of numbers so 40+1, 39+2 until you get 21+20 so ur left with -10(20 pairs of 41) so -10(20x41) = -10(820)= -8200.

Add this to your initial 960 so

-8200 +960 = -7240

Hope this helps

Answer:

Total Platform = 128 ft^3

Step-by-step explanation:

Volume = Length * Width * Height

Left Volume: 2 ft * 4 ft * 3 ft = 24 ft^3

Mid Volume: 4 ft * 4 ft * 5 ft = 80 ft^3

Right Volume: 2 ft * 4 ft * 3 ft = 24 ft^3

Total Volume = 24 ft^3 + 80 ft^3 + 24 ft^3 = 128 ft^3

Answer:

v = [tex]108^{3}[/tex]

Step-by-step explanation:

I'd start with breaking the platform into two parts, the long flat rectangle and then the bit on top. You'll have to add these together at the end!

_________________

So part one: the long piece

formula: v = lwh

dimensions: 12, 3, 2

plug in: v = 12 * 3 * 2

solve: v = 72^3

_________________

part two: smaller rectangle on top ::

formula: v = lwh

dimensions: 4, 3, 3

plug in: v = 4 * 3 * 3

solve:v = 36*3

__________________

now, we add for the total of the entire shape!

final answer: 72 + 36 = 108^3

Answer:

Below!

Step-by-step explanation:

Let us consider that 16 + 4 and 2(2w+8) are equal. Then;

This equation can be solved in two ways. Listed below!

Method 1:

Let's simplify the left-hand-side of the equation.

Then, divide "2" both sides of the equation to open the parentheses.

Subtract 8 to both sides of the equation to isolate the variable (w) and it's coefficient.

Finally, divide 2 to both sides of the equation to isolate the variable (w).

Therefore, 16 + 4 and 2(2w + 8) can be equal if the value of "w" is 1.

Method 2:

Let's simplify the left-hand-side of the equation.

Then, simplify the distributive property to open the parentheses.

Subtract 16 to both sides of the equation to isolate the variable and it's coefficient.

Finally, divide 4 to both sides of the equation to isolate the variable (w).

As said in method 1, 16 + 4 and 2(2w + 8) can be equal if the value of "w" is 1.

Answer:

  C.  The equation has two valid solutions

Step-by-step explanation:

A rational equation like this is often solved by "cross-multiplying" to eliminate the fractions. When we do that, we get ...

  4(2x+10) = x(3x+1) . . . . . . . multiply both sides by (3x+1)(2x+10)

  3x² -7x -40 = 0 . . . . . . . . . . rearrange to standard form

  3x² -15x +8x -40 = 0 . . . . . . separate -7 into factors of 3(-40)

  3x(x -5) +8(x -5) = 0 . . . . . factor pairs of terms

  (3x +8)(x -5) = 0 . . . . . . . finish factoring

The zeros of these factors are not zeros of the original denominators, so neither of the solutions these give is extraneous.

  3x +8 = 0   ⇒   x = -8/3

  x -5 = 0   ⇒   x = 5

Answer:

47%

Step-by-step explanation:

First we need to find the ratio of masks on Jack's wall to the total number of masks, which is 235/500. Now we need to make the denominator 100 in order to find the percentage by dividing the numerator and denominator by 5 to get 47/100. Therefore the percentage of Jack's mask collection that is on his wall is 47%.

Answer:

Angle ADE is an obtuse angle.

Step-by-step explanation:

An obtuse angle is an angle that "opens" greater than 90 degrees. The question asks which angle is an obtuse angle, so basically you follow the order of letters and see which one is greater than 90 degrees (btw, 90 degrees, also known as a right angle, looks like the corner of a square, and anything greater than that is an obtuse angle).

Answer:

An obtuse angle is anything bigger than 90 degrees because 90 degrees is a right angle, therefore D. ADE would be the answer.

Answer:

Equation: N = 2M, Shen needs to read 26 novels in 13 months

Step-by-step explanation:

Given : Shen needs to read 2 novels each month.

i.e. In One month , the number of novels read by Shen = 2

Let N be the number of novels Shen needs to read in M months.

Then , N = 2 M

Thus , the equation relating N to M : N = 2 M

If Number of months = 13 , then put M = 13 in the above equations , we get

N = 2(13) = 26

Hence, the number of novels he read in 13 months = 26.
