Answer:
11
Step-by-step explanation:
W^7/W^-2=W^7+2=W^9 ( when divide subtract the exponent (7-(-2))
W^?/W² = W^?-2
W^9=W^(?-2)
9=?-2
?=11
W^7/W^-2 = W^11/W²
L(which is length) is equal to 42 divided by width which is 6. so the equation is L=42/6
d=2
SHOWN BELOW
2x + 6
= 2(x + 3)
= 2(x) + 2(3)
= 2x + 6
