Area = 1/2 * base * height

202.5 = 1/2 *  base * 15

measure of the base =  202.5 / (1/2 * 15)

rodikova [14]

Answer:

16cats and 19 birds

Step-by-step explanation:

if we say that x is birds and y is cats we can say that:

4.5x+8.5y=221.5 ( the amount birds and cat both need)

y+x =35 (number of cats and cats)

x=35-y

4.5(35-y) +8.5y= 221.5

157.5-4.5y +8.5y =221.5

4y=64

y= 16

16+x=35

x=19

7. y-2 = (x+3)<br> 4<br> 2<br> X<br> - TO<br> 12<br> 4
drek231 [11]

Answer:

y = -24 + -2x + 2x2

Step-by-step explanation:

Simplifying:

y = 2(x + 3)(x + -4)

reorder the terms:

y = 2(3 + x)(x + -4)

multiply (3 + x) * (-4 + x)

y = 2(3(-4 + x) + x(-4 + x))

y = 2((-4 * 3 + x * 3) + x(-4 + x))

y = 2((-12 + 3x) + x(-4 + x))

y = 2(-12 + 3x + (-4 * x + x * x))

y = 2(-12 + 3x + (-4x + x2))

Combine like terms  3x + -4x = -1x

y = 2(-12 + -1x + x2)

y = (-12 * 2 + -1x * 2 + x2 * 2)

y = (-24 + -2x + 2x2)

Solving:

y = -24 + -2x + 2x2

solving for variable 'y'

Move all terms containing y to the left, all other terms to the right.

Simplifying:

y = -24 + -2x + 2x2
