Answer:
A. 3
B. 4.5
Explanation:
A. 2(5x - 3) = 24
10x - 6 = 24
then add six on both sides
U get 10x = 30
divide 10 on both sides
U get x is 3
B. 5(2x + 1) = 50
10x + 5 = 50
minus five on both sides
10x = 45
divide by 10 on both sides
The answer is x = 4.5
C. 1 solution
Step-by-step explanation:
I calculated logically
f(a+h) – f(a)/h = –3
so the answer is –3
the flooor length 360 and the floor breadth 4x90=360
