Can you factor -20x^2+26x+6

Mathematics
1 answer:
saul85 [17]3 years ago
5 0
The first thing I'd do would be to reduce this equation.  Divide all terms by 2:

-10x^2 + 13x + 3 = 0

Then I'd use the quadratic formula.  The roots would be

       -13 plus or minus sqrt(169-4(-10)(3) )
x = -----------------------------------------------------
                             -20

Can you simplify this?  Hint:  sqrt(289) = plus or minus 17.

7. Larry, Moe, and Curly went out on the town one Saturday night. Instead of driving home they thought it would be best to sleep
NARA [144]

Answer:

There is no missing dollar.

Step-by-step explanation:

The question adds twice the $2 kept by the bell boy. Each one paid $9, so $27 of which the room cost 25 and the bellboy kept 2. Each one received 1 dollar back. Room($25)+Bellboy($2)+Change($3)=$30

If we say 27(room)+2(bellboy) you are accounting for the tip twice

If m∠PQR = 141 ° , find each measure.
netineya [11]

Answer:

m<PQS = 82°

m<RQS = 59°

Step-by-step explanation:

m<PQS = (13x + 4)°

m<RQS = (10x - 1)°

m<PQR = 141°

To find each angle measure, find the value of x.

First, get an equation that defines the relationship between the angle measures as follows:

m<PQS + m<RQS = m<PQR (angle addition postulate)

(13x + 4)° + (10x - 1)° = 141°

Use the equation to solve for x

13x + 4 + 10x - 1 = 141

Combine like terms

13x + 10x + 4 - 1 = 141

23x + 3 = 141

Subtract 3 from each side of the equation

23x + 3 - 3 = 141 - 3

23x = 138

Divide each side by 23

23x/23 = 138/23

x = 6

m<PQS = (13x + 4)°

Plug in the value of x

m<PQS = 13(6) + 4 = 78 + 4

m<PQS = 82°

m<RQS = (10x - 1)°

Plug in the value of x

m<RQS = 10(6) - 1 = 60 - 1

m<RQS = 59°
