Answer:
A) 14
Step-by-step explanation:
Take the width: 6 and multiply it 3 times because it says triple.
That gives you: 6 * 3 = 18
Then subtract 4 because it says four inches less than.
That gives you: 18 - 4 = 14
4(x+2)=3(x-2)
Multiply the first bracket by 4
Multiply the second bracket by 3
4x+8=3x-6
Move 3x to the left hand side, whenever moving a number with a letter the sign changes ( positive 3x to negative 3x)
4x-3x+8=3x-3x-6
x+8=-6
Move positive 8 to the right hand side
x+8-8=-6-8
x=-14
Check answer by using substitution method
Use x=-14 into both of the equations
4(-14+2)=3(-14-2)
-56+8=-42-6
-48=-48
Answer is -14- D)
Answer:
the answer is (0,2) (7,8)
