Answer:

x = (64 + 5) ÷ 3

Step-by-step explanation:

                                        3x - 5 = 64

Add 5 to both sides:            3x = 64 + 5 = 69

Divide both sides by 3:          x = 69 ÷ 3 = 23

So the answer is x = (64 + 5) ÷ 3

Note:  If we didn't add the parentheses then using the order of operation x = 64 + 5 ÷ 3 would be x = 64 + \frac{5}{3} = 65 \frac{2}{3}

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!
