4. find the coordinates of the vertices of the figure after the given transformation. reflection across the x- axis k(1, - 1), n(4, 0), (4, - 4)

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

13.46

step-by-step explanation:

16.80 x .20 = 13.46

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
