Answer:

29/30

Step-by-step explanation:

first, we must make sure they have the same denominator!

2/3 x 10/10 = 20/30

3/10 x 3/3 = 9/30

20/30 + 9/30 = 29/30

LU 1<br>- 2x + 3 < 5 and - 4x – 3 > 9

Lynna [10]

Answer: x>-1

x<-3

Step-by-step explanation:

$-2x+3$

subtract 3 on both sides

$-2x$

divide -2 on both sides

$x>-1$

The sign changed because I divided by a negative.

$-4x-3>9$

add 3 on both sides

$-4x>12$

multiply -1 on both sides

$4x$

divide 4 on both sides

$x$

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

azamat

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

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