2 questions 1. Use net to find surface area of prism this is a sqaure the bottom below the line is 12 m the bottom above the line is 5m and the back right height is 9 m. #2 same net surface this is a triangle bottom 19 m bottom side 24 m bottom right height 7 and then the actual angle of the triangle is 25m. Thanks!

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

3

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

answer: about 22.67
