(ab+cd)2 - (ac-bd)2 factorize 2 is power
Answer:
(ab + cd + ac - bd)(ab + cd - ac + bd)
Step-by-step explanation:
(ab + cd)² - (ac - bd)² ← is a difference of squares and factors in general as
a² - b² = (a + b)(a - b)
Here a = ab + cd and b = ac - bd , then
= (ab + cd + ac - bd)(ab + cd - (ac - bd))
= (ab + cd + ac - bd)(ab + cd - ac + bd)

The ordered pairs in the table lie in the graph of the linear function whose equation is
y = 3x + 2.
Which ordered pair does not lie on the graph of this function?
A. (10, 32)
B. (8, 13)
C. (–5, –13)
D. (–8, –22)
y = 3x + 2 = 3 * x + 2
point (10 ; 32) on the line ?
so here we can read : x = 10 and y = 32
if x = 10
then y has to be = 3 * 10 + 2 = 30 + 2 = 32
so yes - on the line
same reasoning for the rest
The ordered pairs which does not lie on the graph of the function are (8,13).
What is function?Function is relationship between two or more variables expressed in equal to form. In a function each value of x must have corresponding value of y.
The value which we put in the function is domain of the function and the value which we will get is known as codomain of the function.
How to find ordered pairs?We have been given a function y=3x+2 and we have to find the ordered pairs which does not lie on graph of function. The ordered pairs which lie on the graph must satisfy the function and the ordered pairs which does not lie on the graph must not satisfy the function.
First ordered pair is (10,32)
32=3*10+2
32=30+2
32=32
It lies on graph.
Second ordered pair is (8,13)
12=3*8+2
12=24+2
12≠26
So it does not lie on graph of function y=3x+2.
Hence the ordered pair which does not lie on the graph of function y=3x+2 is (8,13).

Answer:
Step-by-step explanation:
Given the x-intercepts at -1 and 5, that means y=0 at x=-1 and x=5.
So (x+1) and (x-5) are root for the parabola.
y = (x+1)*(x-5)
That is the quadratic equation for Question B.
Back to A, the x-coordinate of vertex of this parabola is at x=2.
This is because the parabola is symmetrical at its vertex so the vertex must be at the mid-point between its x-intercepts, x=(-1+5)/2=2.

Range of a function is the extent to which any function may be varied. The range of the given function y= -3sin(x)-4 is [-7,-1].
What is a Range?The range of a function is the extent to which any function may be varied.
We know that the general range of the function of sin(x) is between [-1,1].
-1 ≤ sin(x) ≤ 1. . . . . . . . . .(A)
As our required function is y = -3sin(x) - 4
Now, in order to get this function, we will multiply each side in Equation (A) by -3, therefore,
-3 ≤ -3 sin(x) ≤ 3
Further, subtract from 4 from each side of the equation.
-7 ≥ -3sin(x)-4 ≥ -1
Hence, the range of the given function y= -3sin(x)-4 is [-7,-1].

Answer:
x=-1 & y=-9
Step-by-step explanation:
7x-3y=20 ⇒(1)
y=5x-4 ⇒(2)
Multiplying (2) by 3

12 is 30% of ____
(Please explain)
Answer:
40
Step-by-step explanation:
In word problems, the word "of" usually means multiply. Thus, for example, 10% of $50 is $5. This is because we can write 10% as 0.10 or as 10/100 (which is 1/10) and then multiply: (1/10)(50) = 5
So, we often see equations like:
R = (1/2)D meaning R is 50% of D, or R is half of D
Let x = the number we want to find
This problem says:
"12 is 30% of what number?"
12 = (30/100) * x
12 = (3/10)x
(10/3)12 = x [multiply both sides by (10/3)]
40 = x
Checking (very important):
Is 12 = (3/10)(40) ?
12 = (3)(4) ?
12 = 12 ? yes
Answer:
40
Step-by-step explanation:
Let x = unknown number
30% = 30/100 = 0.3
If 12 is 30% of x, then
30% of x is 12
⇒ 0.3x = 12
⇒ x = 12 ÷ 0.3
⇒ x = 40
Or, you can divide 12 by 3 to get 10% and then multiply this by 10 to get 100%:
12 ÷ 3 = 4 (so 4 is 10%)
4 × 10 = 40 (which is 100%)

Write the following ratios in its simplest form 56:112:28
Answer:
2 : 4 : 1
Step-by-step explanation:
First take common factors by factorization.
56 = 14 x 4 = 28 x 2
112 = 14 x 8 = 28 x 4
28 = 14 x 2 = 28 x 1
Remove the 28 common factor.
Therefore,
56 : 112 : 28
= 2 : 4 : 1
