Answer:
X=10, x=4
Step-by-step explanation:
first, divide 14 by 2, and square it; giving you
x^2-14x+(7)^2=-40
Because 7^2 is 49, you have to add 49 to the other side; giving you
x^2-14x+(7)^2=9
Then factor the left side; giving you (x-7)^2=9
Take the square root of both sides, giving you
(x-7)^2= plus or minus 3
Then solve to get two solutions, 10 and 4
D. (5,-21) would be your answer
Answer:
yeah it is 9/16 you just need to subtract 7 from 16 and you get nine, you dont need to change the denominater.
100 is the easiest because 1/100 =0.01
33/100=0.33
