We know that
[surface area]=2*[area of the base]+[perimeter of the base]*height of prism

area of the base= area of <span>a equilateral triangle
b=3 cm
h=2.6 cm
area of the base=b*h/2-----> 3*2.6/2----> 3.9 cm</span>²

perimeter of the base=perimeter of a equilateral triangle
b=3 cm
perimeter=3*(3)-----> 9 cm

[surface area]=2*[area of the base]+[perimeter of the base]*height of prism
[surface area]=2*[3.9]+[9]*6-----> 7.8+54-----> 61.8 cm²

the answer is
61.8 cm²

Your second equation after it has changed, your new equation is y=30x+45

Your slope is 30 and your y-intercept is 45 in this second equation

I hope this helps!

Solve the following inequality: –1 6(–1 – 3x) &gt; –39 – 2x
jeka57 [31]
If you would like to solve the inequality <span>–1 + 6 * (–1 – 3x) > –39 – 2x, you can do this using the following steps:

</span>–1 + 6 * (–1 – 3x) > –39 – 2x
-1 - 6 - 18x > -39 - 2x
-7 + 39 > -2x + 18x
32 > 16x
32/16 > x
x < 2

The correct result would be x < 2.
