Solve If QR = 6x + 1, PR = 14x - 13, and PQ = 5x - 2, find PR
solong [7]

Answer:

P____Q____R

PR= PQ+ QR

(14x-13) = (5x-2)+(6x+1)

14x-13= 11x – 1

14x – 11x = 13–1

3x = 12

x= 12/ 3

x= 4

PR= 14x – 13 = 14 (4) – 13 = 18 – 13= 5

If you want (PQ , QR ) this is the solution

PQ =5x-2=5(4)-2=20-2=18

QR =6x+1=6(4)+1=24+1=25

I hope I helped you^_^

If f(x)=square root 4x+9+2, which inequality can be used to find the domain of f(x)?
jenyasd209 [6]

we have

f(x)=\sqrt{4x+9} +2

we know that

The radicand must be greater than or equal to zero

so

4x+9 \geq0 \\ 4x\geq -9 \\x\geq -\frac{9}{4} \\ x\geq -2.25

the domain is is the interval--------> [-2.25,∞)

therefore

<u>the answer is</u>

4x+9 \geq0

(2x-6)(x +11)<br> What is the answer?
ycow [4]

Answer:

2x^2+16x-66

Step-by-step explanation:

Use FOIL (First, Outside, Inside, Last)

(2x-6)(x+11)

F- 2x*x=2x^2

O-2x*11=22x

I--6*x=-6x

L--6*11=-66

2x^2+22x-6x-66

Combine like terms

2x^2+16x-66
