2. The width of a rectangle is 5 units less than the length. If the area is 150 square units, then find the dimensions of the re
xz_007 [3.2K]

Answer:

  • The length = x = 15 units
  • The width = x-5 = 10 units

Step-by-step explanation:

Let 'x' be the length of a rectangle

As the width of a rectangle is 5 units less than the length.

so

width of rectangle will be = w = x - 5 units

Area = 150 square units

Using the formula

Area = length × width

150=\left(x\right)\left(x-5\right)

150=x^2-5x

x^2-5x=150

Subtract 50 from both sides

x^2-5x-150=150-150

x^2-5x-150=0

\left(x+10\right)\left(x-15\right)=0

if

ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)

x+10=0\quad \mathrm{or}\quad \:x-15=0

x=-10,\:x=15

As length can not be negative. so

x = 15 units

Hence,

The length = x = 15 units

The width = x-5 = 15-5 = 10 units

I’m completely lost can anybody help solve this
Marizza181 [45]

Answer:

\huge\boxed{x=54^o}

Step-by-step explanation:

<em>Look at the picture.</em>

<em />

We have:

l=108^o

Therefore

2\alpha=108^o           <em>divide both sides by 2</em>

\dfrac{2\alpha}{2}=\dfrac{108^o}{2}\\\\\alpha=54^o

Which of the following is the Pythagorean theorem
noname [10]

Answer:

a^2+b^2=c^2

Step-by-step explanation:

The Pythagorean Theorem is used to find a missing side length in a right triangle, and the formula a^2+b^2=c^2 is used to find the missing side, assuming a and b are legs, while c is the hypotenuse.

6. Solve the the following system of equations: 4y+2x=14 2y+2x=10
Inessa05 [86]
4y+2x=14 ==> multiply this 1st equation by (-1) => -4y-2x=-14
Now add it up to the 2nd equation
-4y-2x=-14
 2y+2x=10
--------------    And now add them up
-2y +0x=-4
==> -2y=-4==> 2y = 4 &    y=2                   
Last step: plug y into any equation & you will find x=3

What is the standard form equation of the line shown below?
jolli1 [7]
(-1,5)(2,4)
slope = (4 - 5) / (2 - (-1) = -1/3

y = mx + b
slope(m) = -1/3
use either of ur points (2,4)...x = 2 and y = 4
now sub and find b, the y int
4 = -1/3(2) + b
4 = -2/3 + b
4 + 2/3 = b
12/3 + 2/3 = b
14/3 = b

so ur equation is : y = -1/3x + 14/3....however, this is not ur answer because it is not in standard form.

y = -1/3x + 14/3
1/3x + y = 14/3....multiply both sides by 3
x + 3y = 14 <=== standard form
