Answer:
2x^2 + 7x.
Step-by-step explanation:
8x^2 - 5x + 3x(4 - 2x)
= 8x^2 - 5x + 12x - 6x^2
= 2x^2 + 7x.
H = s-30
188 = h+s
188 = s-30+s
188= 2s-30
218 = 2s
109 = s
109-30 = 79
109 sodas
79 hot dogs
check:
109+79=188
DC/AC=EC/BC
x/(x+3)=10/16
10(x+3)=16x
10x+30=16x
30=6x
x=5
DC=x=5
DC=5 units long
10/16=DE/AB, DE=y
10/16=y/10
16*y=10*10
y=6.25≈6.3
DE≈6.3
There are 16 cups in a gallon, if you multiply 16 by 3, you get 48. So, there are 3 gallons of milk in the Chef's adjusted recipe.
Hope this helped!
Holigina, this is the solution:
Let's recall that √x = x ^(1/2)
Therefore,
√x√x = x ^(1/2 + 1/2) = x^1 (We sum the exponents of the same base)
The correct answer is C. 1
