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

Answer:
v equals 3
Step-by-step explanation:
2 times 3 is 6 and 6 plus 3 is 9 I hope this helps
Start with x=y+13 then plug it in so you get 4(y+13) + 2y = 10
Then you get 4y + 52 +2y =10
Then you add you similarities to get 6y + 52= 10
Subtract 52 from both sides gets you 6y=-42. Then you divide and you get y=-7.
Then you plug that into your original equation so 4x + 2(-7) = 10
4x + -14 = 10
4x = 24
X= 6
Y= -7
