Question Simplify: (-12az2-22³)+(-2a³ +7a²z)-(-4a²z+8az²).

Mathematics

Lorico [155]1 year ago

Step-by-step explanation:

if I take the expression as you wrote it literally, we have

(-12az2 - 22³) + (-2a³ + 7a²z) - (-4a²z + 8az²) =

= -24az - 10,648 - 2a³ + 7a²z + 4a²z - 8az² =

= -24az - 10,648 - 2a³ + 11a²z - 8az²

yet when I assume that there were several typos particularly in the first bracket, my guess about the real original expression is

(-12az² - 2a³) + (-2a³ + 7a²z) - (-4a²z + 8az²) =

= -12az² - 2a³ - 2a³ + 7a²z + 4a²z - 8az² =

= -20az² - 4a³ + 11a²z

The right isosceles triangle shown is rotated about line k with the base forming perpendicular to k. The perimeter of the triang
kipiarov [429]

Answer:

The new shape will be cone with a radius of 17 units, tilt height 24 and units of height k.

Step-by-step explanation:

The image related to the exercise is necessary, to be able to solve therefore the attached one.

We have the following information:

Perimeter of the triangle = 58 units

Hypotenuse = 24 units

We have that the other two sides are equal and have x units, therefore we have the following:

x + x + 24 = 58

2 * x = 58-24

2 * x = 34

x = 34/2

x = 17

Now the triangle rotates around line k , and then it will result in a cone, which is a three-dimensional shape.

Therefore, the new shape will be cone with a radius of 17 units, tilt height 24 and units of height k.

Clare earned a total of $12 for 2 hours of yard work. How many hours in all will it take Clare
Luba_88 [7]

Answer:

3 hours

Step-by-step explanation:

$12 = 2hours

Find how much Clare was paid for one hour

Total money earned ÷ number of hours = wage per hour

12 ÷ 2 = $6 per hour

set up equation

6x = 18

This equation says 6 dollars an hour × number of hours = $18

To solve for this equation, divide both sides by 6 (this isolates the variable)

6x ÷ 6 = 18 ÷ 6

1x = 3

x = 3

Pls look at pic! if u help i’ll give brainliest!!
TiliK225 [7]

Step-by-step explanation:

This is a right triangle with two congruent angles. so this is a isoceles right triangle or called a

45-45-90 triangle. This means that the legs are equal to each other so

3(x + 2)  = 24

3x + 6 = 24

3x = 18

x = 6
