Answer:
C
Step-by-step explanation:
Rectangle: 8*5=40
Triangle 1: (3*5)/2=7.5
Triangle 2: (3*5)/2=7.5
Trapezoid : 40+7.5+7.5=55
<u>11 chairs at each table.</u> (157/14 = 11.214...)
<u>There will be 3 chairs left over.</u> (14x11 = 154 157-154 = 3)
2: A = b*h
A = 4.5*14
A = 63 m^2
3: A = 1/2*b*h
A = 1/2*4*13
A = 2*13 = 26 in^2
Answer:
Step-by-step explanation:
Step 1: Factor left side of equation.
(c+1)(c+9)=0
Step 2: Set factors equal to 0.
c+1=0 or c+9=0
c=−1 or c=−9
C= -1 OR C= -9
