Answer:
Base = 4 units
Height = 8 units
I think the blocks are a unit each and you have to count how much space the triangle is taking up
You take 300 - 99 you get 201 so you still have 201lbs so then 3 times 67 is 201 so it would be B
Answer:
-2
Step-by-step explanation:
Let's call the number x. The statement tells us that
x^2 - 10 = 3x, or
x^2-3x-10 = 0
Factoring:
(x-5)(x+2) = 0. Here, we see that there are two solutions: x = 5 and x = -2. So, the negative solution is x = -2.
Answer:
Midpoint (-1 , 1)
Step-by-step explanation:
Formula: (midpoint)
Let the point A(x , y) be the midpoint of CD.
![x=\frac{x_c+x_D}{2} =\frac{-3+1}{2} =\frac{-2}{2} =-1](https://tex.z-dn.net/?f=x%3D%5Cfrac%7Bx_c%2Bx_D%7D%7B2%7D%20%3D%5Cfrac%7B-3%2B1%7D%7B2%7D%20%3D%5Cfrac%7B-2%7D%7B2%7D%20%3D-1)
![y=\frac{x_C + y_D}{2} =\frac{4+(-2)}{2} =\frac{2}{2} =1](https://tex.z-dn.net/?f=y%3D%5Cfrac%7Bx_C%20%2B%20y_D%7D%7B2%7D%20%3D%5Cfrac%7B4%2B%28-2%29%7D%7B2%7D%20%3D%5Cfrac%7B2%7D%7B2%7D%20%3D1)
Then
A(-1 , 1)
