a. 7a-2b = 5a+b
Answer: The required value of a is
Step-by-step explanation: We are given to solve the following equation for variable a :
To solve the above equation for a, we need to take terms involving a on one side of equality that that involving b on the other side.
So, from equation (i), we get
Thus, the required value of a is
b. 56 − 72 = x
c. 56 + x = 72
d. 56 + 72 = x
Answer:
C. 56 + x =72
(2x - 3)² (squared) simplifies to 4x² - 12x + 9.
The Breakdown
(2x - 3)² = (2x - 3) × (2x - 3)
Using the FOIL method, which stands for First, Outer, Inner, Last, you multiply the terms as follows
First: (2x) × (2x) = 4x²
Outer: (2x) × (-3) = -6x
Inner: (-3) × (2x) = -6x
Last: (-3) × (-3) = 9
Collect the like term
4x² - 6x - 6x + 9
4x² - 12x + 9
(2x -3)²= 4x² - 12x + 9.
