Answer:
Step-by-step explanation:
we are given equation as
Since, we have to solve it by using complete square
so, firstly we will complete square
and then we can solve for x
step-1:
Factor 2 from both sides
step-2:
Simplify it
step-3:
Add both sides 3^2
now, we can complete square
step-4:
Take sqrt both sides
step-5:
Add both sides by 3
we get
Answer:
93
Step-by-step explanation:
There are 70 questions. The probability of getting any one of the questions right is 0.2. That's because there are five answers only one of which is correct.
If there are 5 questions and you want to pick the right one the probability is 1/5. If you don't know how to find that, let your calculator walk you to the answer.
1
÷
5
=
And it will tell you that it is 0.2.
So if you blindly (not brainly) fill in the multiple choice answer sheet, the number you will get right is
(P(0.2) * The total number of questions or
0.2 * 70 = 14
Just pure dumb luck will give you 14 correct answers.
Answer:
A 2(4m + 3) Distribute 8m +6 match
C 8m + 6 This matches
Step-by-step explanation:
18 + 4(m − 3) + 4m
First distribute
18+ 4m -12 +4m
Then combine like terms
8m +6
Now see which expressions match
A 2(4m + 3) Distribute 8m +6 match
D 4(2m + 4) Distribute 8m + 16 no match
B 5m + 19 This does not have 8m no match
E 8m + 16 This does not have 6 as a constant no match
C 8m + 6 This matches
