Help is it A or B? pls help

Damm [24]

Answer:

$f(x)=-(x+8)(x-2)$

Step-by-step explanation:

Start by factoring out a -1...

$f(x)=-(x^2+6x-16)$

Now, we have to find two integers that multiply to get -16 and have a sum of 6:

(-2)*8=-16

-2+8=8-2=6

Using this, we can split 6x into -2x and 8x...

$f(x)=-(x^2-2x+8x+16)$

Factor the first and second half separately...

$f(x)=-[(x^2-2x)+(8x-16)]\\f(x)=-[x(x-2)+8(x-2)]\\$

Since both x and 8 are being multiplied by x-2, we can combine them to get...

$f(x)=-(x+8)(x-2)$

1.4(0.5x+4.2y)−3.5(0.2x−1.5y)<br> simplify<br> lots of points

Vilka [71]

1,4(0,5x + 4,2y) - 3,5(0,2x - 1,5y)

1,4.0,5x + 1,4.4,2y - 3,5.0,2x + 3,5.1,5y

0,7x + 5,88y - 0,7x + 5,25y

0,7x - 0,7x + 5,88y + 5,25y

11,13y

Miss Hutson bought a 14&3 4th pound turkey at $1.84 per pound.what was the cost of the turkey

Morgarella [4.7K]

We have been given that Miss Hutson bought a $14\frac{3}{4}$ pound turkey at $1.84 per pound. We are asked to find the cost of turkey.

To find the total cost of the turkey, we will multiply total pounds of turkey by cost of per pound of turkey.

$\text{Cost of the turkey}=14\frac{3}{4}\times \$1.84$

Let us convert $14\frac{3}{4}$ into decimal form.

$14\frac{3}{4}=14.75$

$\text{Cost of the turkey}=14.75\times \$1.84$

$\text{Cost of the turkey}=\$27.14$

Therefore, the cost of the turkey would be $\$27.14$ .

The perimeter of a pentagon is 20t + 7.

stealth61 [152]

Answer:

3t+11

Step-by-step explanation:

A pentagon has 5 sides

Perimeter is the total measurement around an object=20t+7

we have not been given the 5th side measurement so lets make it x

6t +2t+4t-5+5t+1+x=20t+7

put the liketerm together i e

6t+2t+4t+5t-20t+x=7+5-1

17t-20t+x=11

-3t+x=11

x=11+3t.

So the measurements of the fifth side is 11+3t same as 3t+11
