Step-by-step explanation:

9x² - 4 $y^{6}$

can be factored as a difference of squares , that is

(U + V)(U - V)

9x² - 4 $y^{6}$ = (3x)² - (2y³)²

with U = 2x and V = 2y³

HURRY!!!!<br> What is the equation of the line shown in this graph?

zalisa [80]

Answer:

x = - 2

Step-by-step explanation:

The equation of a vertical line parallel to the y- axis is

x = c

Where c is the value of the x- coordinates the line passes through.

The line passes through (- 2, - 3) and (- 2, 2)

Both of these points have an x- coordinate of - 2, thus

x = - 2 ← equation of line

The length of sides of triangular fields are 10m, 24m and 26m. A farmer grows flowers in this field. If 5kg flowers can be obtai

Ostrovityanka [42]

Answer:

Area: 120m²

Flowers: 600kg

Step-by-step explanation:

we can use Heron's formula to solve for the area.

Heron's formula:

Area of triangle = $\sqrt{ s(s-a)(s-b)(s-c)}$

s = 1/2 (a+b+c)

s = 1/2 (10 +24+26)

s = 30

Area of triangle

$=\sqrt{30(30-10)(30-24)(30-26)} \\=120m^{2}$

Since every 1 m² of area can grow 5kg of flowers,

the yield of flowers will be:

120 x 5

=600kg
