Answer:
-2a^2+3a-6
Step-by-step explanation:
a^2+a-1-(3a^2-2a+5)
=a^2+a-1-3a^2+2a-5
=-2a^2+3a-6
Answer:
#1 . 12.5%
#2. 18.75%
#3. 19%
Step-by-step explanation:
2 / 16 x 100% = 12.5%
15
/ 80 x 100% = 18.75
38
/200 x 100%= 19%
Answer:
Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width. As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s2 (square).
If this is a rectangle, then the answer is the length=96 unitsI just formed two linear equations that follow the information.
1. 2l + 2w= 256
2. l=3w
Then, I solved for w by using substitution. w is 32. I then multiplied it by 3. I get the length as 96.
A new expression can be 5 to 1.5. I can see this because when you divide 500 by 100 it is 5 and when you divide 150 by 100 it is 1.5.
