Hey there!

(-2)2 + (-42) + (18 - 23).

= -2(2) - 42 + 18 - 23

= -4 - 42 + 18 - 23

= -46 + 18 - 23

= -46 + (-5)

= -46 - 5

= -51

Therefore, your answer is: -51

Good luck on your assignment and enjoy your day!

motikmotik

Answer:

1440

Step-by-step explanation:

The sum of the exterior angles of a regular polygon of 10 sides = 360 deg. The sum of the interior angles of a regular polygon of 10 sides = 10*[180 - (360/10)] = 10(180–36) = 10*144 = 1440 deg.

Lily deposited $500 in a savings account. At the end of 1 year, she had earned $20 in simple interest. What interest rate did sh
Vlad1618 [11]
Hi! To find the amount of simple interest earned, we can divide the amount earned in interest by the amount in the savings account. 20/500 is 0.04. To get this in percent form, multiply by 100 to get 4. Lily's savings account received an interest rate of 4%.

Help me Q_Q with this question please
sergiy2304 [10]
The question is how many out of 12 is 1/4? We can do this in a couple of ways. First, set up this equation:

x/12 = 1/4

Solve it by multiplying both sides by 12:

x/12 = 1/4
x = 12/4
x = 3

The other way to solve this is to ask yourself "how many times does 4 go into 12?" The answer there is 3. So 1 * 3 = 3. Either way, Bobby at 3 slices!
