Answer:

Theory

Step-by-step explanation:

Take any 18 objects

For example in this case

Take 18 chocolates

$\frac{1}{6}$ means one sixth , which practically means how many groups of 6 can be formed

So, Try to divide 18 into groups of 6

Count how many such groups are formed(it will be 3)

So one sixth of 18 is 3

That is, 18 comprises of 3 groups, each group containing 6 chocolates

Step-by-step explanation:

Since they already have a common denominator of x+1 we can add the numerators

(2x+4-x+5)/(x+1)

(x+9)/(x+1)

9514 1404 393

Answer:

L'(3, -6)

Step-by-step explanation:

The reflection over the y-axis is modeled by the transformation ...

(x, y) ⇒ (-x, y)

L(-3, -6) ⇒ L'(3, -6)

Point L is located at (3, -6) after the reflection from the 3rd quadrant to the 4th quadrant across the y-axis.

Length of a rectangle is 5 cm longer than the width. Four squares are constructed outside the rectangle such that each of the sq

Answer:

The perimeter of rectangle is $18\ cm$

Step-by-step explanation:

Let

x-----> the length of the rectangle

y----> the width of the rectangle

we know that

$x=y+5$ ----> equation A

$120=xy+2x^{2}+2y^{2}$ ---> equation B (area of the constructed figure)

substitute the equation A in equation B

$120=(y+5)y+2(y+5)^{2}+2y^{2}$

$120=(y+5)y+2(y+5)^{2}+2y^{2}\\ 120=y^{2}+5y+2(y^{2}+10y+25)+2y^{2}\\ 120=y^{2}+5y+2y^{2}+20y+50+2y^{2}\\120=5y^{2}+25y+50\\5y^{2}+25y-70=0$

using a graphing calculator -----> solve the quadratic equation

The solution is

$y=2\ cm$

Find the value of x

$x=y+5 ----> x=2+5=7\ cm$

Find the perimeter of rectangle

$P=2(x+y)=2(7+2)=18\ cm$
