David wants to hang a mirror in his room. The mirror and frame must have an area of 8 square feet. The mirror is 2 feet wide and 3 feet long. Which quadratic equation can be used to determine the thickness of the frame, x?Square with an inner frame with height of 2ft on the left frame and width of 3ft on the top. Arrow on the bottom frame with an x and an arrow on the right frame with an x.


2x2 + 14x − 2 = 0
3x2 + 10x − 8 = 0
4x2 + 10x − 2 = 0
x2 + 7x − 8 = 0

Answers

Represent the thickness of the frame by x. Framing the mirror will increase both its length and width by 2x. The area of the mirror with the frame is the product of the length and width which can mathematically be expressed as,
                                 
                                                A = (3 + 2x)(2 +2x) = 8

The equation above can be simplified into 4x^2 + 10x -2 = 0. This equation can still be further simplified by dividing it by 2. However, it will give an answer which is not found on the choices. Thus, the answer is the third choice.

You cannot bisect an angle using paper folding constructions True or False

Answers

Answer:

The given statement:

You cannot bisect an angle using paper folding constructions is a False Statement.

Step-by-step explanation:

The construction of a angle bisector with the help of paper folding is done by:

  • Draw a angle ACB on a piece of paper such that the ray CB lie on the base.
  • Fold the paper in such a way that ray AC falls along the ray CB.
  • draw the line along the crease that is formed on the paper starting from point C.
  • So, the ray so formed is the angle bisector of the angle ACB.

How to solve this math 3-3x6+2=

Answers

The value of the expression  3-3x6+2 is -13.

What is Expression?

An expression is combination of variables, numbers and operators.

The given expression is 3-3x6+2

Three minus three times of six plus two.

The operators in the expression are plus and minus which are of addition , subtraction and multiplication.

To solve this equation, we need to first multiply 3 and 6, 3×6

which is 18.

we subtract 18 from 3, which is -15.

3-18+2

5-18

When eighteen is subtracted from 5 we get minus thirteen.

-13

Hence, the value of the expression  3-3x6+2 is -13.

Lets change the equation.
3 -(3*6) +2           Multiply 3*6 first and get 18
3 -18+2         -     Same as 3-(18)+2
-15 +2                  3 -18 is the same as doing 18 -3, but with the negative
                             Do the same to -15 +2

Answer is -13
