Write an equation in which the quadratic expression 2x^(2)-2x-12equals 0. Show the expression in factored form and explain what your solutions mean for the equation. Show your work.

Answer:

Answers

Answer:

Begin by factoring 2 out of   2x^2 - 2x - 12 equals 0:

2(x^2 - x - 6) = 0

2(x - 3)(x + 2) = 0.  2 is never zero, but x-3 and x+2 can each be set = to 0:

This results in x = 3 and x = -2.  The equation is true for these two x-values.

w = 7d + 13, which statement is
true?
A. The independent variable is w.
B. The independent variable is d.
C. The dependent variable is 7.
D. The independent variable is 7.

Answers

Answer:

b

Step-by-step explanation:

this is me

The independent variable is found to be d.

What is an independent variable?

An independent variable can be defined as a variable that can take any value which implies it is not dependent on any other variables.

The example can be given as y = x + 2, here x is an independent variable.

The given algebraic expression w = 7d + 13

There are two terms 7d and 13.

Here, the variable term is 7d.

And, the value of w depends on d which implies that d is the independent variable.

Hence, in the given expression the independent variable is d.

Find the value of y in the equation 6(y+4) = 12
Group of answer choices
y = 2
y = -2
y = 8
y = 6

Answers

Answer:

Y= -2

Step-by-step explanation:

6(-2+4)=12

6x2=12

The answer is y= -2. When following order of operations you would divide by 6 on both sides which leaves the equation to be y+4=2 and then you subtract by 4 on both sides. This leave you with y= -2.

Eighty percent of the picture frame is glass. A photo shows a picture frame of length 10 and three-fourth inches and width 8 and one-half inches, hanging on the wall. The border of the frame is labeled molding. What is the area of the molding?

Answers

Answer:

91.4 inches

Step-by-step explanation:

I will leave the explanation in the comments.

The area of the moulding is; 18 and 11/40 square inches

What is the area of the rectangle?

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

Here, we want to get the area of the moulding

we are given that the 80% of the frame is a glass photo

Means 20% of the picture frame will be that of the moulding.

By calculating 20% of the area of the frame, we get the area of the moulding;

43 /4 x 17/2 = 731/8

we have this as;

731/8  divided by 5

= 18 and 11/40 square inches
