<u><em>Answer:</em></u>
c = 4
<u><em>Explanation:</em></u>
The number of solutions for any equation is equal to the degree of the equation.
The given equation is a second degree equation which means that it has two solutions.
The only possible way for it to have one unique real solution is that the two <u>solutions are equal</u>
<u>This means that:</u>
x - 4 = x - c
<u>Now, we solve for c:</u>
x - 4 - x = x - c - x
-4 = -c
c = 4
Hope this helps :)
Answer:
your answer is going to be -158
Step-by-step explanation:
(5)-(3)^2+7×-22=-158
You have 2.50.
3 times 10 is 30, so now you have
2.20.
he bought twice as many six cent stamps as ten cent stamps.
multiples of six that are applicable are 30, 60, 90, 120.
six goes into 30 five times. Five can't be divided in half.
six goes into 60 ten times. ten divided in half is five. fifty plus sixty, is only 110.
six goes into ninety 15 times. fifteen can not be divided in half.
six goes into 120 twenty times. 20 divided in half is ten. ten times ten is 100.
100 + 120 = 220.
He bought 10 10cent stamps
