Answer: 27
Step-by-step explanation:
The expression given is inside a cube root. This is a simplified version of a fractional exponent, 1/3.
We can take the expression outside of the radical to get this:
3 ^ 9 ^ (1/3)
When an exponent is raised to another exponent, multiply the exponents and keep the base the same:
3 ^ (9 * 1/3)
3 ^ 3
The expression is equal to 27.
The value of x that will make the lines parallel is 8
<h3>Corresponding angles </h3>
If the line m and n are parallel to each other hence the given angles will be corresponding angles.
Since they are corresponding angles, hence:
2x² = 128
x² = 128/2
x² = 64
x = √64
x = 8
Hence the value of x that will make the lines parallel is 8

Tammy uses 1 3/4 cups of laundry detergent. The number of loads is 4
<u>Solution:</u>
Given that, Tammy uses 1 3/4 cups of laundry detergent per load.
When she was finished doing laundry one day.
She noticed that she had used 7 cups of laundry detergent.
We have to find how many loads did she do?
Now, we know that, Total cups used can be written as:
<em> </em>number of loads x number of cups per each load = total cups used.
Hence, the number of loads are 4.
Answer:
x=3
y=5
Step-by-step explanation:
3x+2y=19
- 2x+2y=16
_____________
x=3
3(3)=9
19-9=10
10÷2=5
y=5
-162
Because 9 x 2 = 18
18 - 180 = -162
