Answer:
20$
Step-by-step explanation:
A quarter is 0.25 cents so if you have 84 all you gotta do is multiply 84 x 0.25 and the answer is just 21$ so the closest answer is 20$ unless you can add the 20$ with the 1$ bill to get the final answer.
Answer:
3
Step-by-step explanation:
((7x-4)^2) - (7x-4)(7x-4) + 3
(7x-4)(7x-4) is 7x-4^2
So its (7x-4)^2 - (7x-4)^2 + 3
(7x-4)^2 cancel out.
Answer is 3
Answer:
A 3.33
Step-by-step explanation:
20 divided by 6 = 3.333333333333333 and the hundredths place is the second number behind the decimal which would be 3.33
Answer:
tan <F = 1/√3
Step-by-step explanation:
Using the SOH CAN TOA identity
tan theta = opposite/adjacent]
tan < F = GE/FG
Get GE
Using pythagoras theorem
GE² = 14² - (7√3)²
GE² = 196 - 147
GE² = 49
GE = 7
tan<F = 7/7√3
tan <F = 1/√3
So if the measure of angle AMB = 90 so the another right triangle is formed which is ADM, since the it is a right triangle the legs are equal, then the lenght AD = DM and we can solve the length of AM
AM = sqrt( AD^2 + DM^2)
AM = sqrt( 6^2 + 6^2)
AM = 6sqrt(2)
now we can solve the length of AB
AB = sqrt ( AM^2 + MB^2)
AB = sqrt ( 6sqrt(2)^2 + 6sqrt(2)^2)
AB = 12
so the perimeter = 2(6) + 2(12) = 36
