Answer:
D
Step-by-step explanation:
(2x - 3) + [ 4x(3x + 2)]
2x - 3 + [ (4x*3x) + (4x*2) ]
2x - 3 + [ 12x² + 8x ]
2x - 3 + 12x² + 8x
12x² + 10x - 3
Answer:
18 liters
Step-by-step explanation:
Blue : red : White = 5 : 3 : 2
Quantity of Blue paint = 5x
Quantity of Red paint = 3x
Quantity of White paint = 2x
Total paint = 5x + 3x + 2x = 10x
10x = 60 liters
x = 60/10
x = 6
Quantity of red paint = 3x = 3*6 = 18
Answer:
The length is 39.6 feet.
Step-by-step explanation:
Since the area is lw, we make this an equation. The width is already known, it's 26.2. So make a single variable equation: 26.2w=1037.52
dividing both sides by 26.2 gives you the answer of 39.6.
Hope this helps!
Answer:
20.
Step-by-step explanation:
We can begin by calculating 20% of 6:
0.2 × 6= 1.2
If 1.2 is 6% of the number, we can set up an equation like this:
0.06x = 1.2
Now, divide on both sides, giving us:
x= 20.
