Answer:
(A) Mr. Jackson's positive accounts will be removed from his credit report in 10 years.
Answer:
![(3x+3y+9)\ ft^{2}](https://tex.z-dn.net/?f=%283x%2B3y%2B9%29%5C%20ft%5E%7B2%7D)
Step-by-step explanation:
Let
x------> the length of the original play space
y-----> the width of the original play space
we know that
The area of the original play space is equal to
![A=xy](https://tex.z-dn.net/?f=A%3Dxy)
The area of the new play space is equal to
![An=(x+3)(y+3)\\An=xy+3x+3y+9](https://tex.z-dn.net/?f=An%3D%28x%2B3%29%28y%2B3%29%5C%5CAn%3Dxy%2B3x%2B3y%2B9)
Find the difference
![An-A=(xy+3x+3y+9)-(xy)\\An-A= (3x+3y+9)\ ft^{2}](https://tex.z-dn.net/?f=An-A%3D%28xy%2B3x%2B3y%2B9%29-%28xy%29%5C%5CAn-A%3D%20%283x%2B3y%2B9%29%5C%20ft%5E%7B2%7D)
The measure of angle A is 55°.
Solution:
Let us take B be the adjacent angle of 145°.
<em>Sum of the adjacent angles in a straight line = 180°</em>
⇒ m∠B + 145° = 180°
Subtract 145° from both sides.
⇒ m∠B + 145° - 145° = 180° - 145°
⇒ m∠B = 35°
The adjacent angle of 145° is 35°.
In the image, angle B and angle A equal to 90°.
⇒ m∠B + m∠A = 90°
⇒ 35° + m∠A = 90°
Subtract 35° from both sides.
⇒ m∠A = 55°
The measure of angle A is 55°.
The same reason 4 dimes and 4 pennies aren't equal.
To put it into decimal terms, 4/10 is 0.40 (or forty cents), whereas 4/100 is 0.04 (or four cents)
