8x-2= -5+7x
2x= 2x
So you start with one side of the problem and solve it by writing it below. Then do the other side. In the end, they should equal each other
First, we are going to solve the equation to find the value of .
Let's solve the equation step by step
Step 1. Use the distributive property to destroy the parenthesis:
Step 2. Subtract 196 to both sides of the equation:
Step 3. Factor the expression:
Step 4. Set each factor equal to zero and solve for :
or
or
Since we are dealing with lengths here, and lengths cannot be negative, the only valid solution is
Now, we know from our problem that the missing side of the rectangle is given by the expression , so to find the actual length, we just need to replace with 8 in the given expression and simplify:
units
We can conclude that the missing side length represented by x + 8 units of the rectangle is 28 units.
Its 70 because you do 10 time 7
Answer:
g(f(2)) = 41
b)41
Step-by-step explanation:
g(f(2)) = 41
f(2)= 2(2²) + 5 = 13
So g(f(2)) → g(n = 13)
g(n = 13)→ 3(13) + 2 = 41
I believe it should be at (-5,2)
Let me double check tho one sec
