Greeley [361]1 year ago

Answer: -12 but could be wrong

Step-by-step explanation:

I don't know that format but I'm going to take a guess.

x^2 +2x - 8 -(2x+8) then plug in x=2

x^2 + 2x - 8 - 2x - 8

x^2 -16

= 2^2 - 16 = -12

Last Month, Levi had written 125 words of his book. This month,he is up to 12,580 words. About how many times more words has he
VladimirAG [237]

Answer:

He has written about 100 times as many words.

Step-by-step explanation:

In order to find this, we first need to find the number that he has written this month. In order to do so, we need to subtract the previous month from the current total.

12,580 - 125 = 12,455

Now that we have that number, we can divide it by the previous month to see how many times more words he wrote in the second month.

12,455/125 = 99.64 times more, or rounded, about 100 times more.

5 What is the area of a triangle with a base of -7 mm and a height of 10 mm? 0 65 mm 4 0 13 mm 165 mm? 263 mm​
Ghella [55]
First, you have to know the formula of finding the area of a triangle. That is bh1/2. You multiple the base and height together and multiply it by 1/2 or divide by 2. You put in the info they gave you in the formula, after that you get 105/8. That is obviously not one of the choices and it is an improper fraction. The way to make it into a whole fraction is to do 105 divided by 8. Then, you get 13, which is the second answer. Finally, the area of the triangle is 13 1/8 squared mm.

A Ferris wheel has 20 cars that are equally spaced around the circumference of the wheel. The wheel rotates so that the car at t
ss7ja [257]

Answer:

The Ferris wheel rotates 18° between successive cars being at the bottom.

Explanation:

 Angle inside a circle = 360°

 No of cars in a Ferris wheel = 20

 When the bottom of the ride is replaced by the next car, the angle rotated by Ferris wheel is same as the angle between two consecutive cars towards center of Ferris wheel.

  Angle between two consecutive cars of Ferris wheel = 360/20 = 18°

 The Ferris wheel rotates 18° between successive cars being at the bottom.
