Because there's one 3 & four 7's .

Because there are two 2's & four 9's
Expand the expression?
Perform indicated multiplication:
7a(2a)+7a(-5)-4(2a)-4(-5)
14a^2-35a-8a+20 combine like terms, ie (-35a-8a)=-43a
14a^2-43a+20
Answer: g = -4 and h =1 or g= -1 and h = -2
Step-by-step explanation:
If two exponents have the same base and are multiplied together, you will keep the base unchange and add the exponents.
So looking at the equation, the base is 2 for both and they are raised to the powers g and h, meaning that if g and h are added together they have to equal -3.
So find two numbers that their sum is -3.
For example, -1 and -2 add up to -3, -4 and 1 add up to -3.
Answer:
The solution in the attached figure
Step-by-step explanation:
step 1
Place the numbers -4, 4, 0, and -3 in the left side
Adds the numbers
----> is correct
step 2
Place the numbers 3, -1, and -2 in the right side
Adds the numbers
----> is correct
step 3
Place the numbers 1 and 2 in the base side
Adds the numbers
----> is correct
The solution in the attached figure
1 = 1/4(2x+8)
1 = 1/2x + 2
1 - 2 = 1/2x
(-1) = 1/2x
x = (-1) : 1/2 = (-1) × 2/1 = (-2)
Answer : x = (-2)
