Answer:
(x+6)*3
Step-by-step explanation:
You will need to do this equation simply; and in order for that matter.
So you need to use the brackets so you know what comes first.
Remember BIDMAS or BODMAS
BIDMAS: BODMAS:
Brackets Brackets
Indices Order --- (These mean the same thing)
Divide Divide
Multiply Multiply
Addition Addition
Subtraction Subtraction
As you can see the brackets come first, so you do what is INSIDE the brackets before anything. (x+6)
To finish, you will need to multiply, but as it is an unknown, you don't know what to multiply the 3 by.
<u>So x, add 6, then times by 3 = (x+6) *3</u>
Answer:
x=0
Step-by-step explanation:
-2x+9=9
-2x=9-9
-2x=0
x=0/-2
x=0
Answer:
D.
Step-by-step explanation:
The original antenna revolves at a rate of 30 per 2 minutes, or 15 per minute.
Twice as fast = 15 X 2 = 30 per minute
Only the data in Table D fits.
660 / 22 = 30
720 / 24 = 30
Answer:
the second one
Step-by-step explanation:
Answer:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
3*e-4-(6*e*(45+2*e))=0
Step by step solution :

Pulling out like terms
3.1 Pull out like factors :
-12e2 - 267e - 4 = -1 • (12e2 + 267e + 4)
Trying to factor by splitting the middle term
3.2 Factoring 12e2 + 267e + 4
The first term is, 12e2 its coefficient is 12 .
The middle term is, +267e its coefficient is 267 .
The last term, "the constant", is +4
Step-1 : Multiply the coefficient of the first term by the constant 12 • 4 = 48
Step-2 : Find two factors of 48 whose sum equals the coefficient of the middle term, which is 267 .
