Hi there!

<u><em>Answer:</em></u>

<u><em>=128</em></u>

<u><em>*The answer must have a positive sign.*</em></u>

Step-by-step explanation:

<h2><u>Lesson: Order of operations</u></h2>

First, you do parenthesis.

(15-7)=8

Then, you do multiply from left too right.

8*2=16

2^3*16

Next, you do exponents.

2^3=2*2*2=8

8*16

Finally, you multiply by the numbers from left too right.

8*16=128

<u><em>Final answer is 128</em></u>

Hope this helps!

Thank you!

-Charlie

Have a nice day! :)

Yo I need this as soon as possible
joja [24]

Answer:

Step-by-step explanation:

So, if we know that 25 is the area of the square, that means that each side is 5.  That also means the diameter of the circle is 5, so the radius is 2.5.  Now, we can input the radius into the circumference formula for a circle, which is 2πradius.  So, 2π2.5 which equals 5π, or about 15.71

3 numbers are in arithmetic progression their sum is15 and their product is 80 determine the 3 numbers
Mashcka [7]

Answer:

2, 5, 8

Step-by-step explanation:

For starters, let us assume that the numbers are x-d, x, and x+d.

Where d is the common difference between terms.

This mean that we can say, from the question

x-d + x + x+d = 15

3x = 15,

x = 5,

This means that the terms are 5, 5-d and 5+d.

On the other hand,

(5-d) * 5 * (5+d) = 80

(5-d) * (5+d) = 80/5

(5-d) * (5+d) = 16

25 - d² = 16

d² = 9

d = + or - 3.

Finally, the three numbers will be 2, 5, and 8. On the flipside, their sum and product are 15 and 80.
