Answer: r = -11, q =3.5
Step-by-step explanation:
4q – 2r = 36 ....... eqn. 1
6q + r = 10 ..............eqn 2.
from eqn. 2 make r subject formula i.e.
r = 10- 6q (substitute for 'r' in eqn. 1)
we have;
4q - 2(10-6q) = 36 (open bracket)
4q -20 + 12q = 36 (collect like terms)
4q+12q = 36+20
16q = 56
q = 56/16
q = 3.5
substitute for q in eqn. 2.......
6(3.5) + r = 10
21 + r = 10
r = 10-21
r = -11, q =3.5

Answer:
The answer is C.
Step-by-step explanation:
:)
Area of square base:
13 x 13 = 169
Area of triangular sides:
B x H/2
13 x 16/2 = 104
104 x 4 = because there are 4 triangular sides of the figure = 416
416 + 169 = 585in^2
590in^2
