X = 2
y = 1

You can get this by replacing the y in the second equation with the 3x - 5 from the first. Then solve for x. Once you have that value, you can solve for y.

Question 11-(3 marks available)

Answer: 1080 $cm^{2}$

Determine the values of b1, b2, and b3, the sides of the triangular base. Also determine the value of h, the height of the triangular base and l, the length of the prism (the length between the bases).

The sides of the triangular base are:

b1 = 13 in.

b2 = 14 in.

b3 = 15 in.

The triangular base is a right triangle, and so the height is one of our sides. We will use

h = 12 in.

The length of the prism is

l = 20 in.

total surface area = bh + (b1+b2+b3)*l

bh = 12*20 = 240 $cm^{2}$

l * (b1+b2+b3) = 20*(13 + 14+ 15) = 840 $cm^{2}$

TSA = bh + l * (b1 + b2 + b3) = 240 + 840 = 1080 $cm^{2}$
