Step-by-step explanation:
3^-n=0.2
1/3^n=0.2
1=0.2(3^n)
3^n=1/0.2
3^n=5
(3^n)²=5²
(3^n)²=25
The value of the given expression (3^n)^2 is; 25.
Evaluating the value of an expressionFrom the task content, it follows that;
3^-n=0.21/3^n=1/5On this note; it follows that; 3^n = 5.
Consequently, the value of the expression (3^n)^2 is; (5)²
The value of the expression; (3^n)^2 is; 25.

Are the following two expressions equivalent?
Explain how you know...
3(4-x)
6(x+2)-7x
Answer:
no, because the first=12-x
and the second=-1x+2
Step-by-step explanation:
Answer:
No, they are not equivalent.
Step-by-step explanation:
First, we simplify the two expressions.
3(4 - x) = 12 - 3x We multiply everything inside the bracket by 3.
6(x + 2) - 7x = 6x + 12 - 7x = 12 - x Using BODMAS/BIDMAS, we first multiply everything in the brackets by 6 and then simplify.
If we compare 12 - 3x to 12 - x, we can clearly notice that they aren't equivalent. If they were to be equivalent, they would have to be exactly the same values as each other. The 12 is common in both expressions, but the -3x and -x differ, therefore the following two expressions aren't equivalent.

which one is a scaled copy
Answer: D
Step-by-step explanation:
I believe it’s D because a scaled copy is similar to the original shape, but with different shapes. It might be C, but however in math, to make a scaled copy, you have to multiply length number with the same number. (Example: Length is 2, so the scaled copy is 4.)
I hope you have a good day.

Shiva uses 8.2 pints of blue paint and white paint to paint her bedroom walls. 3/4 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Answer: 2.05 pints
Step-by-step explanation:
Shiva used 8.2 pints in total to paint the bedroom.
3/4 of this was blue paint which means that the remaining 1/4 is white paint.
Pints of white paint used:
= Proportion of white paint * Total pints used
= 1/4 * 8.2
= 2.05 pints
A patio 2 pairs of two parallel sides and 2 pairs of sides that are the same length there are 4 square corners what shape is the patio
Answer:
The patio is a rectangle
Step-by-step explanation:
Since it is given that we have 2 pairs of two parallel sides, which implies 4 sides, this thus shows that the shape is a quadrilateral since, only quadrilaterals have 4 sides. Also, 2 pairs of sides are the same length, and are parallel, it shows that the shape is likely a rectangle.
Finally, there are 4 square corners on the shape which implies 4 right angles. This confirms that our shape is a rectangle since only a rectangle has 2 pairs of two parallel sides and 2 pairs of sides that are the same length there are 4 square corners.
So, the patio is a rectangle.
