Do you have a picture of the problem
Answer:
A
Step-by-step explanation:
expanding the bracket, we would have
-2x -18 = -x+1+2
-2x+x= 3 +18
-x=21
x=-21
Answer:
32.8
Step-by-step explanation:
Since the angles given are 90 degrees and 57.2 you can add those together then subtract them from 180 to find the answer 32.8.
180 - 90 + 57.2 = 32.8
Hi there!
Since the formula for finding the perimeter of a rectangle is length×2 + width × 2, we can follow this rule.
2 (4x + 5) + 2 (8x - 4)
= 8x + 10 + 16x - 8
= 24x + 2
So, the perimeter is 24x + 2.
Hope this helps!
