(-2x+4)+2(2x+1)= -2(-x-3)
Answer:
72
Step-by-step explanation:
u can see its a right triangle u can see its kinda like 3-4-5 right triangle
75/5 = 15
21/3 = 7
ok so it doesn't work
now
75^2 - 21^2 = 5184
square root of 5184 = 72
Answer:
c^2 +17c -5
Step-by-step explanation:
I like to line them up vertically
2c^2 +7c - 1
- (c^2 -10c+4)
----------------------
Distribute the minus sign
2c^2 +7c - 1
- c^2 +10c-4
----------------------
c^2 +17c -5
The prediction is 193.86 lb.
Substituting 73 for x, we have:
-102.3923 + 4.0582*73 = 193.86
Answer:
x = 16
Step-by-step explanation:
The two angles are vertical angles, which means they are equal
3x-3 = 2x+13
Subtract 2x from each side
3x-3-2x =2x-2x+13
x-3 =13
Add 3 to each side
x-3+3 =13+3
x = 16
