A.) Blue triangle: 4x+2 + 7x+7 + 5x-4 =
The perimeter of the blue triangle is 16x-5.

Pink triangle: 2x-5 + x+7 + x+3= 4x-5

B.) 16x-5 - 4x-5= 12x

C.) Blue triangle: 16(3)-5= 43

Pink triangle: 4(3)-5= 7

Recall that the perimeter is the sum of all the sides. So, for the first triangle, the perimeter is 4x+2+7x+7+5x-4 = 16x + 5

second triangle: x+3 + 2x-5 + x+7 (combine like terms)

Part b: Subtract the perimeter of the smaller triangle from the perimeter of the larger triangle.

Claire is painting some doors that are all the same size. She used 2 liters of paint to cobe 1 3/5 doors. How many liters of pai

Deffense [45]

Answer:

$1 \dfrac{1}{4} \ liters$

Step-by-step explanation:

Given that:

Claire uses 2 liters of paint to cover 1 3/5 doors

Then in order for her to paint 1 door, She will need:

2 L = 1 3/5 door

x L = 1 door

$x (L) = \dfrac{2 L \times 1 door }{ 1 \dfrac{3}{5} \ door}$

$x (L) = \dfrac{2 L }{ 1 \dfrac{3}{5} }$

$x (L) = \dfrac{2 L }{ \dfrac{8}{5} }$

$x (L) = \dfrac{2 L\times 5 }{ 8 }$

$x (L) = \dfrac{10 \ L }{ 8 }$

$x(L) =1 \dfrac{1}{4} \ L$

If (x+2) Is a factor of x^3-6x^2+kx+10<br> k=?

Arlecino [84]

The value of k is -11

Further explanation:

Any number being a factor states that the value of expression will be equal to zero at the factor.

Given

$x^3-6x^2+kx+10$

and

x+2 is a factor

x+2 = 0

x=-2

If x=-2 is a factor of given expression then the expression will be zero at x=-2

So.

$(-2)^3-6(-2)^2+k(-2)+10 = 0\\-8-6(4)-2k+10 = 0\\-8-24-2k+10 = 0\\-22-2k=0\\-2k=22\\k = -11$

The value of k is -11
