Answer:12
Step-by-step explanation:
The prime factorization of 84 is 2×2×3×7 . The prime factorization of 48 is 2×2×2×2×3 . . Therefore, the GCF is 2×2×3=12
Answer:
-1(x-2)(x-3)
Step-by-step explanation:
first we factor the negative:
-1 (x^2 - 5x +6 )
the next step, (if possible) is to guess 2 numbers that multiplied are 6
and added are -5
in this case is easy to see that those numbers are -2 and -3
The solution then is:
-1(x-2)(x-3)
If guessing the 2 numbers doesn't work, you need to complete the square
1. width=7
2. 7 x 3 = 21
3. length= 21
4. 21 x 7= 147 sq ft
5. length x width = --- sq ft
is this confusing?
hope it helps!
Hey there!
Let's write this as a system of equations.
m+b=31
b= 2m-11
Let's plug our value for b into the first equation and solve for m.
m+2m-11=31
Let's combine like terms.
3m-11=31
We add 11 to both sides.
3m=42
We divide both sides by 3.
m=14
Therefore, Maggie is <u>14 years old.</u>
I hope this helps!
