Step-by-step explanation:

2 \sqrt{7x} .3 \sqrt{14 {x}^{2} }  \\  = 2 \times 3 \sqrt{7x \times 14 {x}^{2} }  \\  = 6 \sqrt{7x  \times 2 \times 7 {x}^{2} }  \\  = 6 \sqrt{2 \times 7 \times 7 \times  {x}^{2} \times x }  \\  = 6 \times 7 \times x \sqrt{2 \times x}  \\  = 42x \sqrt{2x}

Is (2, 3) a solution to the inequality y > 6x + 3?
Sindrei [870]

Good morning

Answer:

NO

Step-by-step explanation:

Here we just substitute x and y by their values and see if the inequality still true or not

y = 3

6x + 3 = 6(2) + 3 = 15

since 3 < 15 then the inequality y > 6x + 3 is wrong.

A regular polygon has a perimeter of 40 cm and a apothem of 6 cm. find the polygons area
Anestetic [448]

Answer:

a = 120 cm²

Step-by-step explanation:

n = number of sides

edge length

40/n

divide the polygon into n congruent triangles

a = (1/2)(edge * apothem) * number of triangles

a = (1/2)(40/n)(6) * n

n cancels out

a = (1/2)(40)(6)

a = 120 cm²
