How to solve this problem
Marysya12 [62]
0.5(x - 3) + (1.5 - x) = 5x
0.5x - 1.5 + 1.5 - x = 5x
-0.5x = 5x
5x + 0.5x = 0
5.5x = 0
x = 0

Question 2 of 10
rusak2 [61]

Answer:

4

Step-by-step explanation:

Since the base angles are the same, the side have to be the same

ML = MN

4x = x+3

Subtract x from each side

4x-x = x+3-x

3x= 3

Divide by 3

3x/3 = 3/3

x = 1

We want the length of MN

MN = x+3 = 1+3 = 4

What’s the area<br> A. 64<br> B. 44<br> C. 30.25<br> D. 13.75
dalvyx [7]

Answer:

B) 44

Step-by-step explanation:

Let's start with the triangles. Normally, when dealing with triangles, you would use the formula (B*H*1/2), but since there's two identical triangles, we can just do (B*H) and get the area for both:

2.5*5.5=<u>13.75</u>

Then to solve for the square, it is also (B*H):

5.5*5.5=<u>30.25</u>

At this point, to solve for the total area, you just add the areas together:

13.75+30.25=<u>44</u>

<u />

Hope this helps!
