Answer:
y = 10x + 6.
Step-by-step explanation:
y = mx + c
Here the slope m = 10 and c = 6 ( the y-intercept)
It's 6 because the point (0, 6) lies on the y-axis (where x = 0).
Answer:
0
Step-by-step explanation:
use this equation to solve for the surface area.
A=2(w+l+hl +hw)
w stands for width
l stands for length
h stands for height
Ok, so you use cross-multiplication.
5 × 9 = 21r
45 = 21r
divide both sides by 21
45/21 = r
Simplify

= r
Have a good day!
