Answer:
4x + 19 = -21
Step-by-step explanation:
4(-10) + 19 = -21
-40 + 19 = -21
X=5/8 or x=-4/3
here is the work if needed...
24x^2+17x-20=0
Step one: Factor left side of equation.
(8x-5)(3x-4)=0
Step two: Set factor equal to 0.
8x-5=0 or 3x-4=0
x=5/8 or x=-4/3

Step-by-step explanation:
For one set the two equations equal to eachother and solve from there. 2 is 45
For three set the two equations equal. Same for four
Answer:
5√202
Step-by-step explanation:
By Pythagoras theorem,
x^2 = 45^2 + 55^2
= 2025 + 3025
x^2 = 5050
x = 5√202
