Answer:
A.
Step-by-step explanation:
To divide the complex number: , we rationalize with the conjugate of the denominator.
This gives us:
We apply the distributive property to get:
We simplify to get:
This implies that:
The correct answer is A.
She tipped 18 percent . 16.50x0.18= 2.97. 16.50+2.97= 19.47
90 = 20 + 70.....GCF of 20 and 70 is 10
90 = 10(2 + 7) <==
can u write another expression using a different common factor...yes
90 = 20 + 70.....common factor is 5
90 = 5(4 + 14) <==
You are totally correct, except for the representation of the formula. If h is 2 times the radius, then h = 2r, and the formula would be
. But your answer is correct. Good job!
