Find the value for x 2x+14=40

Mathematics

1 answer:

Paraphin [41]3 years ago

3 0

Answer: x = 13

Step-by-step explanation:

Reorder the terms:

14 + 2x = 40

Solving

14 + 2x = 40

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-14' to each side of the equation.

14 + -14 + 2x = 40 + -14

Combine like terms: 14 + -14 = 0

0 + 2x = 40 + -14

2x = 40 + -14

Combine like terms: 40 + -14 = 26

2x = 26

Divide each side by '2'.

x = 13

Simplifying

x = 13

The quadrilateral shown is a rectangle. What is the measure of PR? (round to the nearest hundredth)

sladkih [1.3K]

Option B) 37.12 is the right answer

Step-by-step explanation:

It is given that the qudrilateral is a rectangle which means that opposite sides wil be equal and all interior angles will be 90 degrees

PS = 17

PQ = SR = 33

The diagonal PR will form a right-angles triangle with PR being the hypotenuse

So,

Base = SR = 33

Perpendicular = PS = 17

Hypotenuse = PR = ?

The Pythagoras theorem will be used to find the length of PR

So,

$H^2 = B^2+P^2\\(PR)^2 = (SR)^2 + (PS)^2\\PR^2 = (33)^2+(17)^2\\PR^2 = 1089+289\\PR^2 = 1378\\$

Taking square root on both sides

$\sqrt{PR^2} = \sqrt{1378}\\PR = 37.1214$

Rounding off to nearest 100th

PR = 37.12

Hence,

Option B) 37.12 is the right answer
