Answer:

160

Step-by-step explanation:

First, you add 15 + 6 multiplied by 8.

Expression (15 + 6) x 8=?

First, add the expression in the prentice.

15 + 6= 21

Cut out the 10. Why? Because it says make it a triangle. If u did it the other

way it wouldn't make sense.

then multiply 21 and 8

that gives you 160

Which are acute, obtuse, or right?
qaws [65]
5,7 and 8 are right angles, and 6 is an acute angle this is because of u look at 9 and 10 you can see a little box looking thing under the h and if u do that to all of them 5, 7 and 8 can fit the little box but 6 you can’t because it is an acute angle. Hope this helped!

Which choice is equivalent to the product below for acceptable values of X?<br> sqrt(x+2)*sqrt(x-2)
Marizza181 [45]

Answer:

√x^2-4

Step-by-step explanation:

Given the expression

√(x+2) * √(x-2)

= √(x+2)(x-2)

Expand

= √x(x)-2x+2x-2(2)

= √x^2-4

Hence the product of the expression will give √x^2-4

For x to be acceptable x^2 - 4 = 0

x^2 = 4

x = ±√4

x = ±2

Acceptable value of x are values that are greater than or equal to ±2

Explanation:

<u>Part B</u>:

Draw an open circle at x=5. Shade that portion of the number line that exists to the right of the open circle. The solution set is the shaded portion of the number line.

__

<u>Part C</u>:

Any value from the shaded portion of the number line can be used to check the inequality is true. The value at the open circle, or any value to the left of it can be used to check that the inequality is false. For example, one might use values of -5, 5, and 10. Choosing values that are multiples of 5 can make the arithmetic easier.

<u>x = -5 (expect false)</u>

  -2/5(-5) < -2

  10 < -2 . . . . False

<u>x = 5 (expect false)</u>

  -2/5(5) < -2

  -2 < -2 . . . . False

<u>x = 10 (expect true)</u>

  -2/5(10) < -2

  -4 < -2 . . . . True
