Answer:
0
Step-by-step explanation:
4x+ 2( 3 – 3x) = 6
4x+6-6x=6
6-2x=6
6-6=2x
0/2=x
x=0
Answer:
y=2×+1 im a bit rusty hope this helps in some way
D = sq.root of((x2 - x1)^2 + (y2 - y1)^2)
sq.root of 13 = sq.root of((x - (-2))^2 + (1 - 3)^2)
= sq.root of((x + 2)^2 + (-2)^2)
= sq.root of (x^2 + 4x + 4 + 4)
= sq.root of (x^2 + 4x + 8)
Now if we square both sides:
x^2 + 4x + 8 = 13
x^2 + 4x - 5 = 0
(x + 5)(x - 1) = 0
x = -5 or x = 1
Answer:
She messed up the equation, A= B x h, she changed it midway, and also, you need to add the one half to make the equation valid
Step-by-step explanation:
A=1/2 x b xh
17.5 = 1/2 x 5 x h
35=5h (multiply both sides by 2 to get rid of one half)
35/5 = 5h/5
7=h
The height of the triangle is 7 units
Please mark me brainliest, it really helps!
