Answer:
Step-by-step explanation:
3x -8 = 2x + 5
x - 8 = 5
x = 13
3(13) - 8 + 2(13) + 5
39 - 8 + 26 + 5
31 + 31 = 62
Answer:
92%
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
C=9.2v + 21.2
76.4 = 9.2v + 21.2
76.4 - 21.2 = 9.2v
55.2 = 9.2v
v= 55.2 / 9.2 = 6
Area(A)= lw
perimeter(P)= 2w+2l= 34in
length(l)= w+5
width(w)= w
1/2 P= 17= w+l
17= w+(w+5)
17= 2w+5
2w=12
w=6 in
l= w+5
l= 6+5
l=11 in
A= lw= (11)(6)= 66in²
Answer:
Area of rectangle is 66 in².
Answer:
See below
Step-by-step explanation:
y = x^2 (x + 4) - 25(x + 4)
y = (x + 4)(x^2 - 25)
y = (x + 4)(x + 5)(x - 5)
- x - 5 is a yes
- x + 2 is a no
- x - 4 is a no
