Which is equivalent to (4xy – 3z)^2, and what type of special product is it?
16x2y2 +972, the difference of squares
16x2y2+9z2, a perfect square trinomial
16x2y2-24 xyz +9z2, the difference of squares
16x2y2 - 24 xyz +9z2, a perfect square trinomial

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees

you

part a.

angle addition postulate:

if a point lies on the interior of an angle, that angle is the sum of two smaller angles with legs that go through the given point.

from the diagram you can see that point w lies on the interior of an angle, then

m∠uvx=m∠uvw+m∠wvx.

answer: correct choice is b.

part b.

substitution property of equality:

if x = y, then x can be substituted in for y in any equation, and y can be substituted for x in any equation.

given that xy≅yz and xy=4a+4, yz=20, you can substitute instead of xy the expression 4a+4 and instead of yz the expression 20 into the iquality xy≅yz and obtain

4a+4=20

answer: correct choice is a.

5 and 4 because it says f(x) = g(x)
