Answer:
the answer would be B the answer would be B
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
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

- There are 2 triangles (another slanted side) with base 10 and height 12. Thus area would be

- There are two rectangles with base 10 and height 6. Thus area would be

- There are two rectangles with base 14 and height 6. Thus area would be

- 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.
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
