1. Multiply and simplify.
3.xy^4 z^2 . 5x²yx

a. 15(xyz)^11
b. 15x^4y^5z^2
c. 8x^4y^5z^2
d. 15x^2y^4z^2

2. simplify
4x^2 (5x^4 -3x^2 +x-2)
a. -20x^6 + 12x^4 - 4x^3 + 8x^2
b. -20x^8 + 12x^4 - 4x^2 + 8x
c. -20x^6 + 12x^4 + 4x^3 - 8x^2
d. -20x^6 - 12x^4 + 8x^3 -8x^2

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
