Answer:
x = 30 in
Step-by-step explanation:
length of rectangle is (2/3)x + 10; width is (1/3)x + 5;
perimeter is 90 in; find x:
P = 90 in = 2(2/3)x + 2(10) + 2(1/3)x + 2(5), or
90 in = (6/3)x + 30 in
Solving for x, we get (2)x = 60 in, or x = 30 in
Answer:
x=2
x=-5
Step-by-step explanation:
1
Move terms to the left side
2
Subtract the numbers
3
Use the sum-product pattern
4
Factor
5
Create two separate equations
6
Solve
B. yes, because the angles are close enough and the sides are proportional.
10(1/2x+6)=8 is the algebraic equation.
