Answer:
16
Step-by-step explanation:
Write the expression in algebraic form:
3x² + 4y²
Notice we only have variables "x" and "y".
Given these variables: x = 2, y = 1, and z = –3
We can <u>ignore "z"</u> because the variable is not in the equation.
<u>Substitute</u> x = 2 and y = 1 in the expression. In other words, replace "x" and "y" with the numbers they give you.
3x² + 4y²
= 3(2)² + 4(1)²
Then, simplify the expression. Remember to follow <u>BEDMAS order</u> (brackets, <u>exponents</u>, division and <u>multiplication</u>, <u>addition</u> and subtraction).
= 3(2)² + 4(1)² Solve exponents first
= 3(4) + 4(1) Solve multiplication
= 12 + 4 Solve addition
= 16 Answer
The value of 3 x squared plus 4 y squared is 16, if x = 2, y = 1, and z = -3.
