Answer:
What are the solutions of the equation 9x4 – 2x2 – 7 = 0? Use u substitution to solve
Step-by-step explanation:
The answer for this question is x=32
let
y = k/x
where k is proportional constant
putting y = 37 and x =72
37 = k / 72
k = 37 × 72
so now we got value of k
.put it again in equation
y = 37×72/x
let's calculate y when x = 12
y = 37 × 72/12 = 37 × 6 = 222
What is the solution to the equation + 5 = 8?
X=7
X
q
x = 6
Answer:
A) 684 in^2
Step-by-step explanation:
Since it needs to be painted all around the box we have to find the surface area of the box
The surface area of cuboid is
=2lw+2lh+2hw (l: length, w: width, h: height)
=2×15×12+2×6×15+2×6×12
= 684 in^2
