Answer:
yes, if you allow complex numbers; no, if you don't
Step-by-step explanation:
The sum of squares can be considered to be the difference of squares, where one of the squares is negative. The negative square is the square of an imaginary number, so the factoring involves imaginary numbers.
x^2 +25 = x^2 - (-25) = x^2 -(5i)^2
= (x -5i)(x +5i) . . . . factoring in the complex numbers
There is no factoring in real numbers.

f (x) = 4x² -4x
Find f (-7)
Answer:
f(-7) = 224
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightAlgebra I
Function NotationStep-by-step explanation:
Step 1: Define
f(x) = 4x² - 4x
f(-7) is x = -7
Step 2: Evaluate
Substitute in x: f(-7) = 4(-7)² - 4(-7)Exponents: f(-7) = 4(49) - 4(-7)Multiply: f(-7) = 196 + 28Add: f(-7) = 224I don’t know how to do this I’m so confused
Answer:
You have to graph it
Step-by-step explanation:
Step-by-step explanation:
take the value in that BIG curly bracket as X terms....then substitute one by one to the equation given below to get Y values...after that u have cordinates then u can draw the graph..
[tex]x \: \: \: y \\ - 2 = - 8 \\ - 1 = - 10 \\ 0 = - 12 \\ 1 = - 14 \\ 2 = - 16[/tex]
this is for the first equation..so the coordinated are...
(-2,-8), (-1,-10), (0,-12), (1,-14), (2,-16)
use the same methord to find the others

solve for k
9/10 = 10/k
Answer:
k = 100/9
Step-by-step explanation:
In this question, we will be solving for "k".
Solve:
9/10 = 10/k
Cross multiply.
(9 · k) = (10 · 10)
9k = 100
Divide both sides by 9
k = 100/9
Your answer would be k = 100/9
Use the graph to estimate the solution to the quadratic-linear system
From looking at a parabola from a graph, I can kinda figure out the vertex form of it, and then factor it out to standard form.
but, in vertex form, which is a(x=h)+k, how do I figure out the a. usually, it's 1, but if it's not, how do i know that by just looking at the graph

Reduce a ratio 3/4in: 3/16 ft
Answer:
4in : 1ft
Step-by-step explanation:
We start with:
3/4 in = 3/16 ft
This means that the length of 3/4 inches is the same as the length of 3/16 feet.
To reduce this, we can start by dividing by 3 in both sides of the equation:
(3/4)/3 in = (3/16)/3 ft
1/4 in = 1/16 ft
Now we can multiply both sides by 16:
16/4 in = 16/16ft
4 in = 1ft
now we reduced the ratio to:
4in : 1ft

A student draws a quadrilateral that has two sides measuring 5 cm and two sides measuring 8 cm, and the sides opposite to each other are parallel.
Which of the following quadrilaterals could the student have drawn?
Select all that are possible.
A.square
B.rectangle
C.rhombus
D.parallelogram
E.trapezoid
Answer:
B
Step-by-step explanation:
two sides are longer than the other two, D could also be one of the choices but rectangles have two parallel lines and have shorter sides at the sides

Tell whether the ordered pair is a solution to the inequality.
Answer:
If an ordered pair is a solution to an inequality, plug it into the inequality and simplify. If you get a true statement, then the ordered pair is a solution to the inequality. If you get a false statement, then the ordered pair is not a solution.
If y = 3x – 8, and y = f(x), find f(2). *
Answer:
f(2) = -2
Step-by-step explanation:
Replace y with f(x). The equation is now f(x) = 3x - 8. f(2) means that you replace all of the x’s with 2’s. Bringing the equation to f(2) = 3(2) - 8. You now just have to solve the equation. f(2) = 6 - 8. f(2) = -2
