Answer:

130, 131, 132, 133

Step-by-step explanation:

Let the first page numbe be x, the next x+1, x+2, x+3

The sum of the first two will be x+x+1=2x+1

The sum of the last two will be x+2+x+3=2x+5

Product will be (2x+1)(2x+5)

Since the product equals 69165

(2x+1)(2x+5)=69165

4x^{2}+10x+2x+5=69165\\4x^{2}+12x+5=69165\\4x^{2}+12x-69160=0\\x^{2}+3x17290\\(x-130)((x+130)=0\\x=130, -133

Therefore, x=130

Next pages are 131, 132, 133

Answer:

D

Step-by-step explanation:

If you are told that the slope is 2 that means that the equation cannot be A.

The slope is the number in front of the x. So far what you know is that

y = 2x + b

b is found from the given point.

  • x = - 8
  • y = 7
  • 7 = 2*(-8) + b                 Expand the right side
  • 7 = - 16 + b                    Add 16 to  both sides
  • 7+16 = -16 + 16 + b        
  • 23 = b

answer y = 2x + 23

The answer is D

What is the value of x?<br><br><br><br> Enter your answer in the box.
inna [77]

The 3 inside angles of a triangle need to equal 180 degrees.

Since you are given 2 angles, subtract both of those from 180 to find X.

X = 180 - 70 - 30 = 80 degrees.

X = 80
