Answer:

55degrees try it I just wanted to help.

Answer:

A

Step-by-step explanation:

Shift the bottom trinomial to where like terms match up where it looks like this.

2x²+5x+4

5x²+8x

To make it easier to understand add a placeholder +0 to the trinomial so everything matches up so it looks

like this.

2x²+5x+4

5x²+8x+0

Finally, add like terms and you should end up with this. 7x²+13x+4

Answer:

y = 8x^2 + 32x - 96.

Step-by-step explanation:

y=8(x+6)(x-2)

= 8(x^2 - 2x + 6x - 12)

= 8(x^2 + 4x - 12)

= 8x^2 + 32x - 96.

Answer:

-7, -5, -3, -1

Step-by-step explanation:

Let x be the smallest of the four consecutive odd integers. Then the next three consecutive odd integers are x+2, x+4, and x+6. We have:

[tex]3(x + x + 6) = 4(x + 4) - 12[/tex]

[tex]3(2x + 6) = 4(x + 4) - 12[/tex]

[tex]6x + 18 = 4x + 16 - 12[/tex]

[tex]6x + 18 = 4x + 4[/tex]

[tex]2x = - 14[/tex]

[tex]x = - 7[/tex]

So the four consecutive odd integers are -7, -5, -3, and -1.

Answer:

P(Boston Red Sox) = 2/5

Step-by-step explanation:

The probability that the favorite team of a randomly selected baseball fan is the Boston Red Sox can be found by dividing the number of Boston Red Sox fans by the total number of fans.

It's given that there are 12 Boston Red Sox fans and 18 other fans. Therefore the total number of fans is 12 + 18 = 30.

If we divide the number of Boston Red Sox fans by the total number of fans, we get 12/30 = 2/5. Finally, we have P(Boston Red Sox) = 2/5.

C. 4 2/3

Step-by-step explanation:

1) Use this rule: a/b * c = ac/b.

7 * 6/9

2)  Simplify 7 * 6 to 42.

42/9

3) Simplify.

14/3

4) Convert to mixed fractin form.

4 2/3

Answer:

The product of 7/9 and 6:

[tex]\\7/9 x 6 \\\\7x6=42\\\\42/9\\4 6/9\\\\4 is the whole number\\6/9 is the fraction that if we remove the 3 from both of us, it gives us the result 2/3\\ The answer is the B \\[/tex]

Step-by-step explanation:

the answer is the B

Because You only had to multiply 6 by 7 and the result, which would be 42 over 9, should be converted to a mixed number, which would be dividing 42 by 9, which is 4, and us over 6, which is four, which is the whole number, and 6 is the numerator and you don't change the nine since it is still the denominator.

Because the 4 is the whole number

And 6/9 is the fraction that if were move the 3 from both of us , it gives us the result is 2/3

So we have 4 2/3

the answer is the B

Answer:

He Melanie ,  use SOH  CAH  TOA to remember the trig functions

Step-by-step explanation:

for 14 they hyp = 22 and we know one angle of 45°,  we also know that the triangle has a right angle or 90°  and by inspection we can tell that the other angle is also going to be 45°   so we know X and Y will be the same length, is why this is a good observation.  

Use one of the trig functions with H in it b/c you know Hyp is 22,  so,  

SOH  =  Sin(Θ)= Opp / Hyp  

Sin(45) = Opp / 22

Sin(45) * 22 = Opp

[tex]\sqrt{2}[/tex] / 2  * 22 = opp

11*[tex]\sqrt{2}[/tex] = opp     is the exact answer,   if  you would like some decimal places, it's 7.7781 units,  both X and Y

for 15  we can use SOH again for the bigger triangle.  we know the Hyp is 24 and the angle is 30°

Sin(30) = Opp / 24

Sin(30) *24 = Opp

12 = Opp         ( Because I know Sin(30)  = 1/2 )

Opp is the upright between the two triangles

Use CAH   Cos(Θ) = Adj / Hyp

Cos(30) = Adj / 24

Cos(30) * 24 = Adj

[tex]\sqrt{3}[/tex] /2 *24 =Adj

12[tex]\sqrt{3}[/tex] = Adj

Z = 12[tex]\sqrt{3}[/tex]   or if you want some decimals 20.7846

Becasue the smaller triangle is also a 45° right triangle we know that the upright and side Y are the same lengths

then

Y = 12

You could use SOH or CAH  to find the Hyp but, lets just resort to Pythagoras,  and use  his formula to find Hyp

Hyp = [tex]\sqrt{12^{2} +12^{2} }[/tex]

Hyp = [tex]\sqrt{288}[/tex]

hyp = 16.97

X = 16.97

Cost price is the total amount paid for the jacket while the selling price is the amount they are sold. The expression for her total earning willbe t(d) = hd - jp

Cost price is the total amount paid for the jacket while the selling price is the amount they are sold.

Total earning = Selling price  - Cost price

If Dafna makes sport jackets and she is paid d dollars per hour, plus a piece rate of p dollars for each jacket.

Cost price = hd

x is the number of hour

Selling price = jp

total earning = hd - jp

Hence the expression for her total earning willbe t(d) = hd - jp

Since the customers pay 11 dollars for 4 cans, first find how much one can costs by dividing the cost of 4 cans by the amount of cans given.

[tex]11 / 4 = 2.75\[/tex]

Now that we know they're paying 2.75$, multiply 2.75 by 9 to find the result.
