Answer: false
Step-by-step explanation:
The exponents would have to have a different sign from each other (positive or negative), not the integer.
Answer:
x = 5
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x.
Add 3 and subtract 2x from both sides of the equation:
4x (-2x) - 3 (+3) = 2x (-2x) + 7 (+3)
4x - 2x = 7 + 3
2x = 10
Next, isolate the x by dividing 2 from both sides of the equation:
(2x)/2 = (10)/2
x = 10/2
x = 5
5 is your answer for x.

6/16 which is .375, round that to the nearest hundredth and you get .38
Answer: <em>x</em> = -2
Work:
Convert 216 = 6³
Therefore: 6³ = 6^(4x+11)
⇒ Bases cancel out:
3 = 4x + 11 ⇒ Subtract 11 from both sides
-8 = 4x ⇒ Divide both sides by 4
x = -2
Answer:
24a^4 +36a^3+12a^2
Step-by-step explanation:
area = height × width
area= 4a^2(6a^2+9a+3)
area = 24a^4 +36a^3+12a^2
