Answer:

x=-2, x=1/2

Step-by-step explanation:

> 2x²-x=2-4x

> 2x²-x+4x-2=0

> 2x²+3x-2=0

> 2x(x+2)-(x+2)=0

> (x+2)(2x-1)=0

> x+2=0; 2x-1=0

> x=-2; x=1/2

Answer:

Step-by-step explanation:

647 - 574

1.) subtract 7 -4 and you get 3 in the ones place.

2.) next you have to do 4 -7 and you can't do that so you take one from the hundreds place and turn the 6 into a 5.

3. make the 4 a 14 and then subtract 14-7 and you get 7 in the tens place

4.) you are then left with 5-5 in the hundreds place which is 0 so your answer is 73

Hello, please help me!!

ratelena [41]

Answer:

0.14

Step-by-step explanation:

P(A|B) asks for the probability of A, given that B has happened. This is equal to the probability of A and B over the probability of B (see picture)

Here, the question is asking if someone is taking the bus given that they are a senior.

The probability of someone being a senior and taking the bus is 5/100, or 0.05 . The probability of someone being a senior is 35/100, or 0.35

Our answer is then 0.05/0.35 = 1/7 = 0.14

Translate this problem to an equation and solve. The area of a patio is 72 square feet. The length of the patio is 1 foot longer

Inessa05 [86]

A = LW
A = 72
L = W + 1

72 = W(W + 1)
72 = W^2 + W
W^2 + W - 72 = 0
(W + 9)(W - 8) = 0

W + 9 = 0
W = -9......extraneous solution...does not work here

W - 8 = 0
W = 8 <==

L = W + 1
L = 8 + 1
L = 9

so the width (W) is 8 ft and the Length is 9 ft
