This one is a bit confusing but I'll try to answer. Since the sum is given and one of the addend is given, we need to perform subtraction to get the other addend.
8d⁵ - 3c³d² + 5c²d³ - 4cd⁴ + 9 ⇒ SUM
<u>- 2d⁵ - c³d² + 8cd⁴ + 1 </u> ⇒ 1ST ADDEND
6d⁵ - 2c³d² + 5c²d³ -12cd⁴ - 8 ⇒ 2ND ADDEND

<h3>How to simplify an expression?</h3>
The expression can be simplified as follows;
4.5 ÷ 0.25 + 2.5 - 0.75 × 8
Hence, using Pemdas rule,
4.5 ÷ 0.25 + 2.5 - 0.75 × 8
18 + 2.5 - 0.75 × 8
18 + 2.5 - 6 = 14.5
Therefore, she made mistake in her step 2 because she was suppose to solve the multiplication before subtraction.

3,000 in.
(4 x 10) + (7.5 x 10) = 3000
The dimensions on the sketch are 10 times less than the actual rug.
40 in., 7.5 in.
The drawing lengths are ten times more, so you just multiply the dimensions by 10, and then multiply the product you find out to find the actual area of the rug.
Answer:
-1
Step-by-step explanation:
2y+6=1 -3y
add three to both sides and minus 6 from both sides becasue you want to get y by itself
5y=-5
now both sides by 5
y=-1
