Answer:
Step-by-step explanation:
1. The coefficient of 2
is 2. Therefore, the answer is 2 for a. 1 is the coefficient of -x after we add it to the left side. Therefore, b is 1. C is 5, as it is the only whole number.
This means that the answer is a = 2, b =1, c =5.
2. You can simply cancel out both 3s by dividing, which leaves us with 1±9
.
3. The answer is c. Unfortunately, I can't explain that, it's just a well known formula.
I hope this helped!
Let the no be x
4x+9=2x-1
2x=-10
x=-5
Answer:
k = -2.
Step-by-step explanation:
5(3 - 2k) = 2k + 39 Distribute the 5 over the parentheses:
15 - 10k = 2k + 39
15 - 39 = 2k + 10k
12k = -24
k = -2.
Answer:
B
Step-by-step explanation:
You have to evaluate the power and calculate the sum or difference in order to get the answer
your answer would be 33.
step 1
2(+14)−1(2−5)
2+28−1(2−5)
step 2 distribute
2+28−1(2−5)
2+28−2+5
step 3 then add the numbers
2+28−2+5
2+33−2
combine
2+33−2
ANSWER IS
33
