Use the following values to evalaute each expression: W = 13, x = 9, Y = 1.9, Z = 0.5.
Question:
x2 ( is an exponet)+ 4
A. 22
B. 85
C. 1.73
D. 7.61
Pls helpppp
Online "^" is used to indicate an exponent, e.g., x^2 = x squared.
9^2 + 4 = 9*9 +4 = ?
To evaluate the expression x^2 + 4 using the given values, we substitute the value of x, which is 9, into the expression:
x^2 + 4 = 9^2 + 4
We can simplify the exponent first:
9^2 = 9 * 9 = 81
Now substitute the simplified exponent back into the expression:
81 + 4 = 85
Therefore, the value of the expression x^2 + 4 using the given values is 85. So, the correct answer is B. 85.
