Answer:
a=2,b=4. (3a+b)=3*2+4=10.
Answer:
X = 51
Step-by-step explanation:
24 + 27 = 51
x - 27 =
51 - 27 = 24
Heyy I'm not sure if I'm right
12x^4 + 2x^3 - 30x^2
to find the GCF, let's first look at the coefficients.....the GCF of 12,2,and 30 is 2.
as for the variables....pick the one with the smallest exponent...and that would be x^2
so the GCF of this polynomial is 2x^2 <=
The answer is:
Square root of 77

22
You need to rationalize the denominator meaning that you have to get rid of the square root signs in denominator
To get rationalize the denominator you need to multiply both sides by square root of 11
(Square root of 7)(square root of 11)
——————————————————
2(square root of 11)^2
When squaring a square root it makes the square root “go away”
(Square root of 77)
——————————
2(square root of 11^2 or 122) = 2(11)
So:
The answer is
square root of 77

22
~~hope this helps~~
Answer:
Step-by-step explanation:
lets break down 120 to see what it is divisible by and see if any of those numbers are perfect squares.
120/2=60
120/3=40
120/4=30
we can stop there because 4 is a perfect square and 30 can not be reduced any further to produce a perfect square.
do not forget there is only one x so it must stay in side the radical.
your answer is 2sqrt(30x)
