Answer:

If it says (10a + 4): 40a + 16

If it says (10a - 4): 40a - 16

Step-by-step explanation:

If it's an equilateral quadrilateral, that means all sides are equal. So you would multiply the given side by the number of sides. Then simplify you equation.

I can't read it if it says (10a + 4) or (10a - 4) so i'll just do both and you can use which one it says.

If it says (10a + 4):

4(10a + 4)

40a + 16

If it says (10a - 4)

4(10a - 4)

40a - 16

The quotient of a number x and −1.5 is 21

Andru [333]

Answer:

x = -31.5

Explanation:

We are given that the quotient of x and -1.5 is 21

This means that:

$\frac{x}{-1.5} =21$

To get the value of x, we will multiply both sides of the equation by -1.5

This means that:

$\frac{x}{-1.5} * -1.5=21*-1.5$

x = -31.5

Note that the value of x must be negative because we are dividing by a negative number and the quotient is positive (-ve/-ve is +ve and +ve/-ve is -ve)

Hope this helps :)

Angie read 22 pages during a 30-minute study hall. At this rate, how many pages would she read in 45 minutes

frosja888 [35]

45 minutes is equal to 1.5 times 30:

1.5*30=45

so she will also read 22*1.5 pages, which is 22+11=33

so she will read 33 pages
