Answer:
B. y=x^2 +7x +10
Step-by-step explanation:
Answer: 27
Step-by-step explanation:
Hi, to answer this question we have to apply proportions:
Michael hits the bulls-eye on a dart board 18 out of 30 tries
The proportion is: 18 hits / 30 times= 18/30
For 45 times:
x hits / 45 times
Where x is the number of hits out of 45 times.
So:
18/30 = x/45
Solving for x:
[18/30] 45 = x
x =27

im just saying we both copyed off of another question no solving involved
1) In this problem, we can see that this is an isosceles right triangle.
2) So, one way of solving it is to make use of the Pythagorean theorem. Note that an isosceles triangle has two congruent sides, so we can write out:
Usually, we rationalize it. But since the question requests the denominator to be a rational one, so this is the answer.
