Question 13(multiple choice worth 5 points) (05.06 lc)the net of an isosceles triangular prism is shown. what is the surface area, in square units, of the triangular prism? three rectangles are shown, one below the other. the middle rectangle has a width of 6 units, and, along each width, is a triangle with a height of 4 units. the length of the lowermost rectangle is 8 units and its width is 5 units. 104 units2 132 units2 152 units2 168 units2

for number one its -x+10y=14x+10y=21 the next one is Simplifying

-7x + -5y = 11

Solving

-7x + -5y = 11

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '5y' to each side of the equation.

-7x + -5y + 5y = 11 + 5y

Combine like terms: -5y + 5y = 0

-7x + 0 = 11 + 5y

-7x = 11 + 5y

Divide each side by '-7'.

x = -1.571428571 + -0.7142857143y

Simplifying

x = -1.571428571 + -0.7142857143y
