Answer:

15ab

Step-by-step explanation:

When you multiply out the square (p+q)^2, you get the trinomial ...

(p +q)^2 = p^2 + 2pq + q^2

Your binomial is (3a+2.5b), so you have ...

p = 3a

q = 2.5b

and the trinomial you get when you multiply it out is ...

(3a)^2 + 2(3a)(2.5b) + (2.5b)^2

= 9a^2 + 15ab + 6.25b^2

The first and last of these terms are shown on the right side of the given expression, so to finish out the identity, you need to replace * with 15ab.

Answer:

m<CBD = 68 degrees

Step-by-step explanation:

Add both of the given angle measures and set them equal to 90 degrees.

4x + 52 + 8x - 10 = 90    Combine like terms

12x + 42 = 90

      - 42  - 42                  Subtract 42 from both sides

12x = 48                           Divide both sides by 12

x = 4

Now plug this into the equation for m<CBD

4(4) + 52       Multiply

16 + 52          Add

68 degrees

If this answer is correct, please make me Brainliest!

olga nikolaevna [1]

The value of x that makes the equation 6x=322 true is x=53.67

Step-by-step explanation:

We need to find the value of x that makes the equation 6x=322 true

The equation given is:

6x=322

Divide both sides by 6

6x/6=322/6

stiv31 [10]
No, I do not agree.

one bat hous holds about 3000 bats => 300 bats / house

So, to estimate the number of bats holded by 12 bat houses do>

300 bat / house * 12 house = 3600 bats

That is very far from the 4500 bats that Larry says.

You run 1 3/4 miles each day. Your friends runs 4 times as far as you do. How far does your friends run each eah day?
MrMuchimi
⓵ You run 1 ¾ miles. You can decide to work with fractions, but I find it easier to work with decimals :

¾ = 3 ÷ 4 = 0,75

1 mile + 0,75 mile = 1,75 miles

⓶ Your friend runs 4 times as far as you do, wich means that he runs 1,75 miles times four :

1,75 x 4 = 7 miles

So your final answer is : Your friend runs 7 miles each day.

I hope this helped, if there’s anything just let me know! ☻
