Could someone possibly help me with this

Mathematics
1 answer:
Sergio [31]3 years ago
3 0

Answer:

40

Step-by-step explanation:

The shape has 6 sides a,b,c,d,e,f

The perimeter is the sum of the sides

P = a+b+c+d+e +f

4 of the sides add to 195  a+b+c+d = 195  Replace in the equation

P = 195 +e+f

We know that e and f are equal

P = 195+f+f

P = 195+2f

The perimeter is 275

275=195+2f

Subtract 195 from each side

275 -195 = 195+2f-195

80 = 2f

Divide by 2

80/2 = 2f/2

40 =f

The other 2 sides are 40 ft each

First simplify it so it would become -1 x^2 over 6 x^5
then you need to simplify the x's so do 5-3 so the final answer is -1 over 6 x^3

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
