Number 6 is B because each input or x value has one output or y value
Number 7 is C because that’s not even an equation
Number 8 is D because each input or x value has one output or y value
Number 10 is A because if you graph it all of the points would be on a line increasing proportionally
(Hopefully this made sense I tried my best)

Simplify. √20 * √3 * √18<br><br><br> 5√10<br> 6√10<br> 5√30<br> 6√30
natulia [17]

Answer:

D: 6√30

Step-by-step explanation:

Simplify the following:

sqrt(20) sqrt(3) sqrt(18)

sqrt(18) = sqrt(2×3^2) = 3 sqrt(2):

sqrt(20) sqrt(3)×3 sqrt(2)

sqrt(20) = sqrt(2^2×5) = 2 sqrt(5):

2 sqrt(5) sqrt(3)×3 sqrt(2)

2×3 = 6:

6 sqrt(5) sqrt(3) sqrt(2)

sqrt(5) sqrt(3) sqrt(2) = sqrt(5×3×2):

6 sqrt(5×3×2)

5×3 = 15:

6 sqrt(15×2)

15×2 = 30:

Answer: 6 sqrt(30)

The flag of a country contains an isosceles triangle. (Recall that an isosceles triangle contains two angles with the same measu
Nady [450]

Answer:

Let us start with the unknown. Let us give one of the base angles the value of x. The other base angle is also x since both the base angles in an isosceles triangle will be equal. The remaining angle is 40 more than three times one of the base angles.It is 3x + 40. Here we get the equation

x+x+3x+40=180

5x + 40 = 180

5x = 180 - 40 = 140

Therefore x = 140/5 = 28

So the angles are 28, 28 and 124.

The third angle is 3 times 28 + 40 = 84 + 40 = 124.
