Answer:
Total weight of gravel on the roof = 
Step-by-step Explanation:
The area Adams planned to cover with gravel can be divided into 3 rectangles as shown in the diagram attached.
We would have 3 rectangles. See the attachment below to check out how we arrive at the dimensions of the 3 rectangles.
Area of rectangle = L*W
Area to be covered by gravel = area of rectangle 1 + area of rectangle 2 + area of rectangle 3
Area to be covered with gravel = 
Total weight of gravel on the roof = 12 pounds per square foot multiplied by total area of the roof to be covered = 
Answer:
135y/o
105years apart
Step-by-step explanation:
Assuming that every mother in the family has their child at 15, Jessica‘s great great great great great great grandma is 135 (45 +15years for every 'great')
Jessica is fifteen (fifteen years younger than her mom, who is 30), so she and her great great great great great great grandma are 105 years apart.
First, we want to subtract function f minus function g to get a new function:
(f-g)(x)= x+12 - (-2x)
(f-g)(x)= x+12+2x
(f-g)(x)= 3x+12
Now, we want to plug in 144 for x:
<span>(f-g)(144)=(3)(144)+12
</span>(f-g)(144)=432 +12
<span>(f-g)(144)=444
</span>
Therefore, the answer is 444
Graph C because it goes through the point (1,0)
The statement for geometric model using algebra tiles represents the factorization is the statement number 2.
<h3>What is algebra tile?</h3>
Algebra tiles used to represent the algebraic expression in the table form. The shape of algebra tile is square and rectangle, in which the variables represented.
The given polynomial equation in the problem is,
In the above polynomial, the highest power of variable is 2. Thus, it is a quadratic equation.The image of the algebra tile for the given polynomial attached below.
The statement which satisfy the polynomial and its algebra tile is,
An algebra tile configuration.
- 3 tiles are in the Factor 1 spot: 1 is labeled x and 2 are labeled negative.
- 3 tiles are in the Factor 2 spot: 1 is labeled x and 2 are labeled negative.
- 11 tiles are in the Product spot: 1 is labeled x squared, 4 are labeled negative x, and 6 are labeled.
Thus, the statement for geometric model using algebra tiles represents the factorization is the statement number 2.
