Answer:

4x + 8

-45 - 5x

7x - 21

Step-by-step explanation:

For the first one

4(x + 2)

for distributive property you multiply the number or symbol next to the outside of the parenthesis, by everything inside the parenthesis.

4(x+2)

4*x = 4x

4*2 = 8

So, this is 4x + 8

-5(9+x)

-5*9= -45

-5*x=-5x

So, this is -45 - 5x

7(x-3)

7*x= 7x

7*-3= -21

This will be 7x - 21

Hope this helps!!

Answer:

Step-by-step explanation:

I can tell you how to do this on your calculator, but I have no idea what kind of calculator you have and the methods are different for the various TI graphing calculators, so I'll just tell you that your answer is the last choice given. It's a terrible fit, but if the instructions say linear, the last choice is the equation that the calculator gives.

Answer:

a) Angle XBC = 55 because XY is parallel with BD

b) As given, XB = XC, so that triangle XBC is the equilateral triangle.

As XBC is equilateral triangle, angle XBC is equal to angle XCB

Angle XBC = 55° => Angle XCB = 55°

In a triangle, the total value of three corners are equal to 180°

So that: Angle XBC + Angle XCB + Angle BXC = 180°
