Answer: -135
Explanation:
1) I will use synthetis division
2) Write the coefficients of the divisor in order
1 -3 7 5
3) Dividing by x + 4 => use x = - 4
4) Division:
| 1 -3 7 5
|
- 4 | -4 +28 - 140
-------------------------------
1 -7 35 - 135
5) The last number is the remainder: - 135
7/2= 3.5 phone calls per hour. Hope Thai helps!
Probability of getting a pen in the first box:
7/12 = 0.58
0.58 x 100% = 58%
probability of getting a crayon in the second box:
5/10 = 1/2
half of 100 is 50, so 50%
or:
1/2 x 100% = 50%
Answer:
Step-by-step explanation:
We need to simplify . First of we need to know what LCM is, it is the lowest common multiply of two terms or numbers but in this case we are simplifying an algebraic expression so it is terms. Also we need to remember that since we have numbers and letters we must extract the LCM first then do the division so,
12xy ÷ 4y² → First of all we can cancel out the 12 and 4 by 3 and 1
3xy ÷ y² → Then the top y can cancel out with y² so on the numerator there no 'y' and on the denominator there is 'y'
The final answer is
Answer:
