Answer:
area=144
Step-by-step explanation:
so we need to find the length of each side
since its a square there is 4 sides
perimeter is all the sides added up
48/4=12
the formula for a squares are is b*h
12*12= 144
(fg)(x) = [f(x)][g(x)]
(fg)(x) = (4x - 5)(3) = 12x - 15
Answer:
28a + 35
Step-by-step explanation:
When you are using the distributive property, you need to multiply the number right outside of the paranethesis to both numbers. In this case, that number is 7. 4a and 5 are in the paranthesis, so we need to multiply 7 to 4a and 5. In the end, we get 28a and 35 or 28a + 35
