The answer is 36 pi square inches
Hope this helps.
S=2(4x+2x)+4x^2=4x^2+12x
4x^2+12x=7
4x^2+12x-7=0
D=12^2-4x4x(-7)=256
X1=(-12-16)/(2x4)=-3.5 impossible
X2=(-12+16)/(2x4)=0.5
A
Answer:
56
Step-by-step explanation:
Recall that 1 lb = 16 oz, meaning that 1/2 lb = 8 oz.
Thus, we need only divide 28 lb by 1/2 lb to determine the number of 8 oz servings are contained in a 28 lb bag of dog food:
28 lb
--------------------- = 56 8-oz servings
1/2 lb/ serving
3*2=6
2 2/3
7*2=14
2 5/7
the answer is B)
good luck
Slope = 2/3
y = mx + b
6 = 2/3(3) + b so b = 4
equation
y = 2/3x + 4
3y = 2x + 12
answer is c.3y = 2x + 12
