Jackie didn’t subtract 12 from 8 right, I think
Answer:
<em>Explanation to the answer below... (Answers in the Explanation</em><em>)</em>
Step-by-step explanation:
We Know that our rule is y =
, which means we can use this rule to find y from x. Since we don't know what X, is, we have to assume numbers like 1, to 7. And there is no space to write on the graph, I'll put a virtual copy of a graph.
1st Point,

2nd, point

3rd Point

4th Point

5th Point

6th Point

7th Point (Last Point)

Let's now plot them on the Graph, the values are so big, the graph might look a little odd.
Always remember that we can continue the points infinitely, and there is no stop, The Graph is attached below...
Answer:
(a + 2b)(a - b)
Step-by-step explanation:
Assuming you require the expression to be factored
Given
a² +
ab - b² ← factor out
from each term
=
(a² + ab - 2b²) ← factor the quadratic
Consider the factors of the coefficient of the b² term(- 2) which sum to give the coefficient of the ab- term (+ 1)
The factors are + 2 and - 1, since
2 × - 1 = - 2 and 2 - 1 = + 1, thus
a² + ab - 2b² = (a + 2b)(a - b) and
a² +
ab - b² =
(a + 2b)(a - b)
Answer:
see explanation
Step-by-step explanation:
The area (A) of a square is calculated as
A = s² ( s is the measure of a side of the square )
Here s = x + 2 and A = 7, thus
(x + 2)² = 7 ← expand left side using FOIL
x² + 4x + 4 = 7 ( subtract 4 from both sides )
x² + 4x = 3 ← as required
If this was a cone, the volume would be 314.16.
- You would just put in the radius and height in the cone volume formula which is πr²h 1/3
If this is a cylinder then the volume would be 942.48
- Put in the radius and height in the cylinder volume formula which is πr²h
