Answer: It's D.) factor
Step-by-step explanation: You factor both numerator and denominator
To solve a quadratic equation using completing the square method,
STEP 1
Divide through by the coefitient of the squared term.
Looking at the solutions of Rashid and Tia, we notice that Rashid did not divide through by the coefficient of

.
Therefore, Rashids solution is wrong.
We solve the equation using completeing the square as follows:
Answer:
Option A, 5/8 - 6/8
Step-by-step explanation:
<u>Step 1: Find a common denominator</u>
5/8 is good
3/4 -> 3*2 / 4*2 -> 6/8
<u>Step 2: Combine</u>
5/8 - 3/4 is now 5/8 - 6/8
Answer: Option A, 5/8 - 6/8
The radius is 1/2 the diameter so 17 inches. In one turn you will go about 44 inches. The circumference.
Answer:
x^2 + -2 sqrt(7) x + 7
Step-by-step explanation:
Expand the following:
(x - sqrt(7))^2
(x - sqrt(7)) (x - sqrt(7)) = (x) (x) + (x) (-sqrt(7)) + (-sqrt(7)) (x) + (-sqrt(7)) (-sqrt(7)):
x x - sqrt(7) x - sqrt(7) x - (-sqrt(7) sqrt(7))
(-1)^2 = 1:
x x - sqrt(7) x - sqrt(7) x + (sqrt(7))^2
x x = x^2:
x^2 - sqrt(7) x - sqrt(7) x + sqrt(7)^2
Cancel exponents. (sqrt(7))^2 = 7:
x^2 - sqrt(7) x - sqrt(7) x + 7
Combining like terms, sqrt(7) x (-1) + sqrt(7) x (-1) = -2 sqrt(7) x:
Answer: x^2 + -2 sqrt(7) x + 7
