It will be y+3y and the answer is 4y
Answer:
B.
Step-by-step explanation:
The ratio of the lengths of the sides of a 30-60-90 triangle is
1 : sqrt(3) : 2
From the 1 and 2, we see that the hypotenuse must be twice the length of the short leg.
From the 1 and sqrt(3) we see that the long leg is sqrt(3) times the length of the short leg.
Now we check for these two ratios in each choice.
A.
1 is twice 1/2. Check
sqrt(3)/2 is sqrt(3) times 2. Check
B.
10 is twice 5, not twice 5/2. This does not check.
C.
2sqrt(2) is twice sqrt(2). Check
sqrt(6) is 2sqrt(2) time sqrt(3). Check
D.
6 is twice 3. Check
3sqrt(3) is sqrt(3) times 3. Check
Answer: B.
Answer:
x² + 3x - 10
Step-by-step explanation:
Each factor in the second factor is multiplied by each term in the first factor, that is
x(x - 2) + 5(x - 2) ← distribute each parenthesis
= x² - 2x + 5x - 10 ← collect like terms
= x² + 3x - 10
P = m+n/q
by timesing by p then dividing by q
1 hour = 60 minutes
60 minutes ÷ 5= 12
Answer is 12
