Answer:
part a. A
part b. x + 6
part c. (4x – 1)(3x + 6)
Step-by-step explanation:
width + x + x = 3x + 6
width = 3x + 6 – x – x /answer for part a/
width = x + 6 /answer for part b/
Area = (length)(width) = (4x – 1)(3x +6) /part c/
4/5×1/2= 2/5.
If you want your answer in decimal form than it would be 0.4.
Answer: Multiplied by 10
Step-by-step explanation:
Answer:
7.3 in
Step-by-step explanation:
Area of triangle = (1/2) *b*h
27 = (1/2) * x^2
54 = x^2
square root (54) = x
x=> 7.3484....
Rounding off to 1 decimal place, you get 7.3 in.
