Question

100 - x^2При x равном минус 5С объяснением

Answer 1

100 - (-5)² = 100 - 25 = 75

или так:

100 - х² = (10-х)(10+х) = (10-(-5))(10+(-5)) = (10+5)(10-5)=15 * 5 = 75

Answer 2

$100 - x ^{2} = 100 - 5 ^{2} = 100 - 25 = 75$

Answer 3

To evaluate the expression 100 - x^2 when x is equal to minus 5 (x = -5), we need to substitute -5 for x in the given expression and perform the calculations:

Expression: 100 - x^2

Substitute x = -5 into the expression:

100 - (-5)^2

Now, calculate the value of (-5)^2:

(-5)^2 = (-5) * (-5) = 25

Now, substitute the value back into the expression:

100 - 25

Finally, perform the subtraction:

100 - 25 = 75

So, when x is equal to -5, the value of the expression 100 - x^2 is 75.
