Answer:

Step-by-step explanation:

(a + 3)×(−2a² + 15a + 6b²) =

= a×(−2a² + 15a + 6b²) + 3×(−2a² + 15a + 6b²) =

= -2a³ + <u>15a²</u> + 6ab² - <u>6a²</u> + 45a + 18b² =

= -2a³ + 9a² + 6ab² + 45a + 18b²

Amira is painting a rectangular banner 2 1/4 yards wide in the cafeteria. The banner will have a blue background. Amira has enou

Dominik [7]

we know that

the area of the rectangular banner is equal to

$A=W*h$

where

W is the wide of the banner

h is the height of the banner

in this problem

$W=2\frac{1}{4} \ yards=\frac{(4*2+1)}{4} =\frac{9}{4} \ yards$

$A=1\frac{1}{2} \ yards^{2} =\frac{(1*2+1)}{2} =\frac{3}{2} \ yards^{2}$

In the formula of the area solve for h

$A=W*h\\ \\ h=\frac{A}{W}$

Substitute the values of W and A

$h=\frac{\frac{3}{2}}{\frac{9}{4}} \\ \\ h=\frac{2}{3} \ yards$

therefore

the answer is

the height of the banner is $\frac{2}{3} \ yards$
