Answer:
b
Step-by-step explanation:
B= 3
(7+5b)+1
(7+5(3))+1
(7+15)+1=23
22+1=
23
Answer:
x = sqrt(11)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the sides and c is the hypotenuse
x^2 +(sqrt(5))^2 = 4^2
x^2 +5 = 16
x^2 =16-5
x^2 = 11
Taking the square root of each side
x = sqrt(11)
Answer:
168
Step-by-step explanation:
Surface area= 2(WL+HL+HW)
2×(4×6+6×6+6×4)
=168
It should be A. You would keep the 5, and the exponent should be 4+8, which is 12.
