Answer:
11. x = 5
12. x = 24
Step-by-step explanation:
11.
8x° + 140° = 180°
(Linear pair angles)
8x° = 180° - 140°
8x° = 40°
x ° = 40°/8
x° = 5°
x = 5
12.
2x° + 42° = 90°
(complementary angles)
2x° = 90° - 42°
2x° = 48°
x ° = 48°/2
x° = 24°
x = 24
Cylinder SA=2πrh+2πr<span>2
</span>Rectangular prism SA=2(wl+hl+hw)for the cylinder
SA= 904.78
for the rectangular prism
-you know that all the sides are 8 cm
h- 14
w-8
l-8
SA= 576
Add both together and you should get
1480.78
answer: it is correct :The equation is not quadratic in for because it cannot be written as a second degree polynomial
explanation : if the leading term had x^2, then it would be quadratic, but it's not
