First expand it
Next subtract 14 - 2x + 4x so it can be 14 + 2x
Next subtract 14 from both sides
Next subtract 20 - 14 so it can be 6
Then divide both sides by 2
And lastly reduce the fraction 6/2 and once u reduce it u have your answer which is x = 3.

In rhombus ABCD, the diagonals AC and BDintersect at E. If AE=5 and BE=12, what is thelength of AB?
hram777 [196]

Diagonals that bisect each other are perpendicular and form a right angle.

AEB is a right triangle.

We can apply the Pythagorean theorem:

c^2 = a^2+b^2

Where c is the hypotenuse (longest side) and a and b the other 2 legs.

Replacing:

AB^2 = AE^2+BE^2

AB^2 = 5^2+12^2

AB^2 = 25+144

AB^2 = 169

AB=√169 = 13

Lenght of AB= 13

What are the answers I have to put in the yellow boxes?
valentinak56 [21]

The expression 1x² + 14x + 40 is a quadratic expression, and the answers in the yellow boxes are 40 and 14

<h3>How to complete the boxes?</h3>

The quadratic expression is given as:

1x² + 14x + 40

This implies that:

a = 1

b = 14

c = 40

Because a quadratic expression is represented as:

ax² + bx + c

The expressions in the yellow boxes are:

a * c and b

So, we have:

a * c = 1 * 40 = 40

b = 14

Hence, the answers in the yellow boxes are 40 and 14
