What is the distance between points A and B?
Galina-37 [17]

Answer:

6 units

Step-by-step explanation:

We require to calculate the absolute value so as to consider the measure both ways, that is

AB = | 1 - (- 5) | = | 1 + 5 | = 6

BA = | - 5 - 1 | = | - 6 | = 6

WILL MARK BRAINLIEST<br> the last two pics are for question two
DanielleElmas [232]

Answer:

1. 702 square centimeters

2. m∠YWX = 63°

Step-by-step explanation:

1.

The total surface area is area of all the sides.

  • There are 2 triangles (slanted side) with base 14 and height 11. Thus area would be  2(\frac{1}{2}*14*11)=154
  • There are 2 triangles (another slanted side) with base 10 and height 12. Thus area would be  2(\frac{1}{2}*10*12)=120
  • There are two rectangles with base 10 and height 6. Thus area would be  2(10*6)=120
  • There are two rectangles with base 14 and height 6. Thus area would be  2(14*6)=168
  • The bottom is a rectangle with area 10 * 14 = 140

Adding all these up  154 + 120 + 120 + 168 + 140 = 702 centimeters square.

2.

Angle WYX is equal to 46° (vertical angles are equal).

Now looking at triangle XWY, we know all three angles will add up to 180°. Given x =71° and Y = 46°, we can figure out W (Angle YWX)

71 + 46 + Angle YWX = 180

Angle YWX = 180 - 71 - 46 = 63°

Second answer choice is correct.

Which expression is equivalent to 4x - (3x2 + x) + 5 - (2x2 + 1)?
creativ13 [48]
4x - (3x^2 + x) + 5 - (2x^2 + 1)

4x + x - 3x^2 - 2x^2 + 5 + 1

= 5x - 1x^2 + 6

Therefore the equivalent is 5x - 1x^2 + 6
