<span>Exponents are the repeated multiplication of a
number. It is represented by the formula of a^n where a is the number to be
repeated and n is the number of times the number is being multiplies by itself.
Also include the sign of the number, no matter how it is multiplied, it is
still important. In this problem, you have 4 as the repeated number. You can
see that it is multiplied by itself by two times. So you have (-4)^2.</span>
19. There are 24 hours in a day and Maria travelled for 15 days so multiply the two:
24*15=360
So Maria travelled for 360 hours.
22a. False; 2,000 lbs = 1 Ton
22c. True; 48 oz = 3 lbs
I think the answer is C but I’m not 100%
Answer:
<u>The answer is none.</u>
Step-by-step explanation:
<h2><u>
Because</u></h2><h2><u>
Side of the square is greater than breadth of rectangle. </u></h2><h2><u>
Answer: How can this be possible? Side of any square cannot be more than breadth of rectangle unless and until the square is bigger than the rectangle.</u></h2><h2><u>
Side of the square can be greater than length of triangle: </u></h2><h2><u>
Answer: Not at all possible. How can the length of a square be greater than the length of a rectangle? then the square would no longer have the same sides. And as i said before, squares cant be long unless and until they are bigger than the rectangle.</u></h2>

a. Does her equation make sense?
If so, explain why her equation must be true. If it is not correct, determine what is incorrect and rewrite the equation.
b. If you have not already done so, solve her equation, clearly showing all your steps.
What are the measures of the two angles?
c. Verify that your answer is correct.
The figure is attached below
Given : (2x+1) + (x-10) = 90
(a) Yes , the equation make sense because right angle is 90 degree. Also two angles make up 90 degree.
(b) solve for x, (2x+1) + (x-10) = 90
2x+1 + x-10 = 90 ( combine like terms)
3x -9 = 90 (add 9 on both sides)
3x = 99
x = 33
One angle is 2x+1 = 2(33) +1 = 67 degrees
Another angle = x-10 = 33-10 = 23 degrees
(c) one angle + another angle = 90
67 + 23 = 90
So verified
