Drops = 27
First, we need to find the volume of the given tank using the following equation
Now that we know the volume, we need to find out how many drops that we need to use. We can find that out using the following equation
Answer:
y² + y + = (y +
)²
Step-by-step explanation:
In most cases, we can factor a polynomial, or quadratic, by looking at the factors of the last term. In this case, the last term is . When we factor a polynomial, we are looking for two expressions that when multiplied together using FOIL (forward-outside-inside-last) will give us the polynomial. For example: (a + b)(a + b) or (a+ b)².
In order to get y² + y + , we are looking for a 'c' value that will add up to '1' which is our 'b' value (ay² + by + c).
Since
Then, we can use as our factor for both expressions. Putting this together we get: (y +
)(y +
) or (y +
)²
Answer:
114.8 cm^2
Step-by-step explanation:
<h2><u>Finding the area of the shape </u></h2>we can break down this figure into individual shapes :
- rectangle
- triangle
- parallelogram
<h3><u>area of a triangle</u></h3>formula:
<u>area of a triangle =25.2 cm^2</u>
<u />
<h3><u>area of a rectangle</u></h3>formula:
4.5 * 8
<u>area of a rectangle = 36 cm^2</u>
<u />
<h3><u>area of parallelogram</u></h3>formula:
1/2 * ( sum of parallel sides ) * height
1/2 * ( 8 + 8 ) * 6.7
<u>area of a parallelogram = 53.6 cm^2</u>
<u />
<h3><u>Total area</u></h3>= area of rectangle + area of triangle + area of parallelogram
= 25.2 + 36 + 53.6
<h2><u>= 114.8 cm^2</u></h2>
