Answer:
The area of the dilated square is 28 m^2
Step-by-step explanation:
we know that whenever any figure is dilated by a factor 'b' units
so, area will be dilated by b^2 units
Here , we are given figure is dilated by 7 units
so, area will be dilated by 7^2
we are given
Area of square is
now, we can multiply by 7^2
and we will get area as
So,
The area of the dilated square is 28 m^2
The equivalent expression on expanding -1/4 (-8x + 12y) is 2x - 3y
<h3>Expansion of expression</h3>
Expansion of expression can be carried out using the distributive rule a shown:
A(B + C) = AB + AC
Note that <u>A is distributed over B and C</u>
Given the expression
-1/4 (-8x + 12y)
-1/4(-8x) - 1/4(12y)
2x - 3y
Hence the equivalent expression on expanding -1/4 (-8x + 12y) is 2x - 3y

Answer: D. 48 degrees.
Step-by-step explanation:
Answer: -12
Step-by-step explanation: To solve this problem, we can first start by rewriting the problem. When we add a negative, that's exactly the same thing as subtracting so we can make the problem easier to understand.
18 + (-30) → 18 - 30
To find the answer to this problem, let's first find out how many jumps it get's to 0 from 18. It would take 18 jumps and there is 12 jumps left over. Then, we would subtract 12 from 0 and we would get -12 as our answer. Therefore, 18 + (-30) = -12.
