Answer:
A=0.5(a+b)h
=0.5(27+17)4=88units^2
Step-by-step explanation:
Answer:
a=4
Step-by-step explanation:
8x-8+3ax=5ax-2a
Get all the terms with a on the right side
Subtract 3ax from each side
8x-8+3ax-3ax=5ax-3ax-2a
8x-8 = 2ax -2a
Factor out an 8 on the left and 2a on the right
8(x-1) = 2a*(x-1)
Divide by (x-1) on both sides
8(x-1)/(x-1) = 2a*(x-1)/(x-1)
8 = 2a
Divide by 2
8/2 =2a/2
4 =a
In the second one I'm pretty sure you just measure the length of the points.
Answer: y=3
Subtract the bottom left of the triangle from the number at the top of the triangle. Then that number is multiplied by the number at the bottom right of the triangle.
To solve:
6-5=1
1•3=3
y=3
Answer:
Direction
Step-by-step explanation:
Multiplying a vector by a positive scalar numbers impacts its horizontal and vertical components by the same proportional amount, but doesn't change its direction.
