Answer:
expression: w - 7
phrase: 7 less than a number
Step-by-step explanation:
-3p^3 + 5p -2p^2 - 4 - 12p + 5 + 8p^3
5p^3 - 2p^2 - 7p + 1
It is the second choice
Answer:
$38.42
Step-by-step explanation:
Answer:
15%
Step-by-step explanation:
900/6000
which is the same as 900÷6000
900÷6000= 0.15
0.15 as a percent in 15%
Area = l•w
length= 2x+1 width= x
210 = (2x+1)(x)
distribute x
210 = 2x^2 + x
move 210 to other side
2x^2+x-210 = 0
factor the polynomial
(2^x2+21x)-(20x-210)=0
x(2x+21)-10(2x+21)=0
(x-10)(2x+21)=0
x=10, -21/2
measurements can’t be negative so x=10
the width is 10
the length is 2(10)+1=21
