What is the volume of a rectangular prism with the dimensions: base 2 1 2 cm, height 1 1 2 cm, and length 3 1 2 cm?

a) 13 1 8 cm3

b) 8 1 2 cm3

c) 7 1 2 cm3

d) 6 9 16 cm3

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52

step-by-step explanation:

answer: i could not see part the question so ill explain how to get the answer

step-by-step explanation: for instance the distance she travele d is 10 and she traveled the same amout each mile so do 10 divided by how many miles she drove each time and you ge your answer.

alright so i think for this one it would to draw it out. this may be hard for me to try and draw, but i will do my best on here:

        r

  /       |     \

notice how it forms 2 triangles inside one bigger triangle.

so if we know the angle spr is the same as psr that is saying the measure of angle p is the same as angle s. this means the big triangle psr is either isosceles or equilateral. in both cases, the triangle is perfectly symmetrical when split down the middle, which is in this case rq. because we know it is perfectly symmetrical on both sides, we know that the two triangles inside the bigger one are equal.
