Answer:

Step-by-step explanation:

KL = 12 because the triangle is isosceles ( base angles are congruent)

KJ = JM = 12 because the triangle is equilateral ( all angles are equal 60°)

the perimeter is

P = 9 + 12 + 12 +12 = 9 +36 = 45

Write down and simplify the following algebraic expressions. The sum of −3x+5 and 7−4x is subtracted from 5x+17.

andriy [413]

Sum of the first two is:
-3x+5+7-4x = -7x+12
That subtracted from 5x+17:
5x+17-(-7x+12) = 12x+5

We can see here that there are 2 triangular bases on the prism.

To calculate the area of a triangle, we multiply the base and the height and then divide by 2.

A = 8 x 6 /2

A = 48/2

A = 24

Hope it helps!
