Answer:

Step-by-step explanation:

Use the quadratic formula to find the roots of x²+8x+15

x = [-8±√(8²-4·1·15)]/[2·1] = [-8±√4]/2 = -3, -5

make factors from the roots

x²+8x+5 = (x+3)(x+5)

jamal is going to borrow 14000 from his credit union to buy a used car. the APR is 7.0% and the length of the loan is 4 years. h
ELEN [110]
The formula to use here would be:

A = P(1+r)^t  where P is the principal (starting) amount, r is the rate of interest, and t is time. Knowing this, plug in your values:

A = 14,000(1+0.07)^4 once worked out, you should get $18,351.14414 < this is the total amount he would be paying at the end of 4 years. to find the interest, subtract this amount from the principal amount (14,000):

$18,5351.14414 - 14,000 = 4,351.14414 < this is the amount of interest. Round your answer. 

Answer: Jamal will pain $4,351.14 interest.

Sam has the lead role in the school play. He still has to memorize 1/2 of his lines. Suppose Sam memorizes 1/3 of his lines toda
DaniilM [7]

Answer: 1/6

Step-by-step explanation:

Since Sam has to memorize 1/2 of his lines and he memorizes 1/3 of his lines today, the fractions of his lines that he has left to memorize will be gotten by subtracting 1/3 from 1/2. This will be:

= 1/2 - 1/3

= 3/6 - 2/6

= 1/6

Therefore, he has 1/6 of his lines left to memorize.

inessss [21]

Answer:

The answer to your question is:

Step-by-step explanation:

  m ∠ 1  = 27°

 m ∠ 1 and m ∠ 2 are supplementary

m ∠ 1 + m ∠ 2 = 180°

27° + m ∠2 = 180°

m ∠ 2 = 180° - 27°

m = 2 = 153°
