By the pythagorean theorem we know that.
s2 = r2 + h. ...
since r = a/2.
s2 = (1/4)a2 + h2, and.
s = √(h2 + (1/4)a2)
This is also the height of a triangle side.
I don’t know the answer but this might help.
x = -3/4 = -0.750
x = 5/3 = 1.667
The first term is, 12x2 its coefficient is 12 .
The middle term is, -11x its coefficient is -11 .
The last term, "the constant", is -15
Based on the area of the tabletop with the inner circle, the area after the inner circle has been cut out is 12,309 inch².
<h3>How do we find the new area of the tabletop?</h3>
We are told that the area of the tabletop is 12,463 inch².
We then need to find the area of the circlular cutout as:
= π x radius x radius
= 3.14 x 7 x 7
= 154 inch²
The new area after the cutout is removed is therefore:
= Current area - area of circular cutout
= 12,463 - 154
= 12,309 inch ²
Rest of the question:
Area of table including the cutout is 12,463 square inches.

Answer:
x=4/3
Step-by-step explanation:
2+4=2(x-1) original
6=2(x-1) combine like terms
6=2x-2 multiply x-1 by 2
8=2x add 2 to both sides
4=x divide both sides by 2
Answer:
B. 24d + 4; $76
Step-by-step explanation:
Part 1: If the online store charges $24 per DVD, this is the same as saying "24 multiplied by the number of DVDs bought".
It's given that "d" represents the number of DVDs
- So the first part of the variable expression is: 24d
If the online store also charges an additional $4 per <em>order,</em> that means that it's only $4 extra for the whole order. NOT per DVD you buy.
Part 2: If someone were to buy 3 DVDs, that would mean that d = 3.
To find the total cost, substitute 3 for d into the expression.
- 24d + 4
- 24(3) + 4
- 72 + 4 = 76
- Result: $76
