Answer:
w=16, L=20
Step-by-step explanation:Length(L)=w+4
P=72
P=2L+2w
P=2(w+4)+ 2w
P=2w+8+2w
72=4w+8
4w=72-8
4w=64(/4)
w=16
L=16+4=20
Verification: 16+16+20+20=72
32+40=72
72=72 (T)
Answer:the answer is 1
Step-by-step explanation:
2(4y-1)=6
Divid by 2 on both sides
4y-1=3
Add 1 to both sides
4y=4
Divid both sides by 4
Y=0
14.
1. 7 × 7 = 49
2. 7 × 3 × 3 = 63
3. 7 × 3 × 4 = 84
4. 7 + 3 + 4 = 14
