Answer:
Rather than just multiplying 5/4 with 8, she has to multiply it with 3 + 8. She could put parentheses around the 3 + 8, according to PEMDAS, this would mean that the parenthesis must be solved before multiplication. The correct answer would be:
4/5x - 8 = 3
4/5x = 3 + 8
x = (3 + 8)5/4
x = 11 x 5/4
x = 55/4 or 13.75
18 by 39.
Reason:
2x+2y=114 (perimeter)
XY=702 (area)
X=18
Y=39
Step-by-step explanation:
a(n) = a +(n-1)d
a=13
d=9-13=5-9=-4
°.° a(n) = 13 +(n–1)-4
hope this helps
Step-by-step explanation:
since x=2 and z=-2
4+4=8 [ because -2* -2=+4 ]
