Taman bunga berbentuk persegi Panjang dengan ukuran panjang diagonalnya
( 4x + 15 ) meter, lebarnya ( 6x + 3 ) meter. panjang diagonal sebenarnya

The English question states:

Rectangular flower garden with length  (4x + 15) meters, width (6x + 3) meters. The actual diagonal length of the flower garden is?

____________________________

In this case, we have a rectangular flower garden with a diagonal length  (4x + 15) meters and width (6x + 3) meters. By Pythagorean theorem we have that the diagonal (D) is:

3333333333333333333333333333333333333333333333

step-by-step explanation:

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
