Answer:
8 sqrt(5)
Step-by-step explanation:
sqrt(45) + sqrt(125)
Rewriting
sqrt(9*5) + sqrt( 25 *5)
we know sqrt(ab) = sqrt(a) sqrt(b)
sqrt(9) sqrt(5) + sqrt(25) sqrt(5)
3 sqrt(5)+5 sqrt(5)
Add like terms
8 sqrt(5)
Answer:-24
Step-by-step explanation:
6+(-5-7) ➗ 2-8(3)
6-12 ➗ 2-24
6-6-24
0-24=-24
Answer:
4a2−b2−2a+b, there are no factorable rational numbers.
Step-by-step explanation:
Let x represent the cost of corn dogs. Let y represent the cost of pretzels.
2x+3y=13
5x+6y=28
Multiply the first equation by two so that we can eliminate y.
Subtract:
4x+6y=26
5x+6y=28
-x=-2
x=2
4(2)+6y=26
8+6y=26
6y=18
y=3
3 x 2 = 6
6+2=8
Therefore, 2 pretzels and a corn dog would cost $8.
With 433 dollars, you can buy 24 boxes of fixtures. When you buy 24 boxes, you will have 1 dollar left.
