What is the value of the expression shown below if x = 3, y = 6, and z =<br> 4?<br> x² + 3yz
Karo-lina-s [1.5K]

Answer:

81

Step-by-step explanation:

The initial expression:

x^2+3yz

Identify your values:

x=3\\y=6\\z=4

Substitute:

(3)^2+3(6)(4)

Following PEMDAS, nearly everything is in parentheses, so move to exponents:

9+3(6)(4)

Multiply 6 and 4:

9+3(24)

Multiply 3 and 24:

9+72

Simplify:

A) 60<br> B) 120<br> C) 30<br> D) 90
melamori03 [73]

Answer:

The answer would be B) 120

Step-by-step explanation:

In the triangle with angle 2 and 3, it has a right angle in it, making angle 2 and 3 added together 90 degrees. But you have to figure out what angle 2 and 3 equal. Well the whole triangle is equilateral, making all three angles equal to 60 degrees. Angle 3 is half of 60 degrees because it is split by the dotted line. This makes angle 3 equal to 30 degrees. Now you can find the measure of angle 2. 30(angle 3) plus 90(right angle) equals 120 degrees. This makes angle 2 equal to 60 degrees. In this image, angle 2 is half of angle 1. So angle one is equal to 120 degrees. I hope this helps.
