Answer: ( P - 10 )/12, (2x + 5)(4x + 1)

Step-by-step explanation:

The length of the rectangle = 4x + 1,

The breadth = 2x + 5

Formula for finding perimeter of a rectangle, = 2( L + B )

Now, substitute for L and B in the formula, open the formula and simplify,

= 2(4x + 1 + 2x + 5 )

= 2(6x + 5 )

= 12x + 10

Therefore, the perimeter (p)of the rectangle, = 12x + 10.

If P = 12x + 10

12x = P - 10

x = ( P - 10 )/12

Area of a rectangle = L x B

=( 4x + 1 )( 2x + 5)

We therefore open the brackets

(4x + 1)(2x + 5)= 4x X 2x + 4x X 5+ 1 X 2x + 1 X 5

= 8x² + 20x + 2x + 5

A = 8x² + 22x + 5

A = (2x + 5)(4x + 1)

Answer: 199 square yards

Step-by-step explanation:

If you break it down into 3 rectangles it’ll be easier to find the answer. Multiply it by H x W. First you do the 6 x 10. And then afterwards add the extra 5 to the 6 and it’ll make the

H = 11, and the W is 4. And then add the last 3 to H and it’ll make it 19 and the last W is 5

6 x 10 = 60

11 x 4 = 44

19 x 5 = 95

Total of 199

Hope this helps :)

34 of 136 in fraction form
solong [7]

Answer:

\frac{1}{4}

Step-by-step explanation:

One of the methods is to first split the face and the denominator of the fraction into first bases:

\frac{34}{136}  =  \frac{2 \times 17}{2 {}^{3}  \times 17}

Let's simplify:

\frac{2}{2 {}^{3} }  =  \frac{1}{4}

600 or 600 decreased by 20% and then increased by 20% of the result? Which amount is larger and by how much
ohaa [14]

Answer:

The initial value of 600 is larger and larger by 24.

Step-by-step explanation:

First of all a 20% decreased of 600.

So, the new value will be 600(1 - \frac{20}{100}) = 600 \times 0.8 = 480.

Now, then it is increased by 20% i.e. 480 will be increased by 20%.

So, the new value will be 480(1 + \frac{20}{100}) = 480 \times 1.2 = 576.

Therefore, the initial value of 600 is larger and larger by (600 - 576) = 24. (Answer)
