Answer:
155
Step-by-step explanation:
5*5=25
((5*13)/2)*4=130
130+25=155
Answer:
(-5,1)
Step-by-step explanation:
Add it together
3x - 2x = x
y - y = 0
9 - 14 = -5
x = -5
Choose a random equation, doesn't matter.
3x + y = -14
3(-5) + y = -14
-15 + y = -14
y = -14 + 15
y = 1
Answer:
(x + 5)^2 = (5 - 3)^2
Step-by-step explanation:
Given the equation;
x^2 + 10x + 22 = 13
We have;
x^2 + 10x = 13 - 22
x^2 + 10x = -9
Adding half of 10 to both sides and completing the square as usual, we have;
(x + 5)^2 = 5^2 + (-9)
(x + 5)^2 = (5 - 3)^2
