Answer: The answer to the first question is 20
Step-by-step explanation:
Answer:
-8
Step-by-step explanation:
If 3x-4y=2, then for any number a we also have a(3x-4y)=a(2) by multiplication property of equality.
Therefore, for a=-4 we have -4(3x-4y)=-4(2) which means the value of -4(3x-4y) is -8.
If x=2
length=2
width=2+1
=3
length × width = area
2×3=6
the answer for length is 2 ,while for the width is 3
By adding 3 to both sides and dividing both sides of the equation by 4 you end up with x=6
answer is x =6
Hope this helps!!
