Answer:

x = -1, -5

Step-by-step explanation:

{(x + 3)}^{2}  = 4 \\  =  >  {x}^{2}  + 2 \times x \times 3 +  {3}^{2}  = 4 \\  =  >  {x}^{2}  + 6x + 9 = 4 \\  =  >  {x}^{2}  + 6x = 4 - 9 \\  =  >  {x}^{2}  + 6x =  - 5 \\  =  >  {x}^{2}  + 6x  + 5 = 0 \\  =  >  {x}^{2}  + 5x + x + 5 = 0 \\  =  > x(x + 5) + 1(x + 5) = 0 \\  =  > (x + 1)(x + 5) \\  =  > x =  - 1 \:  \: or \:  \:  - 5

If the seed company recommends planting approximately 350 grass seeds per square meter, about how many grass seeds will he need?
Svetach [21]

Answer:

83422.5 grass seeds

Step-by-step explanation:

Applying,

A = 1/2bh....................... Equation 1

Where A = Area of the Triangle, b = base, h = height.

But, from the diagram,

tanФ = 20/b

b = 20/tanФ.................. Equation 2

Substitute equation 2 into equation 1

A = 1/2(20/tanФ)(h)................ Equation 3

Given: h = 20 m, Ф = 40°

Substitute these values into equation 3

A = 1/2(20×20)/tan40°

A = 200/tan40°

A = 238.35 m²

If the seed company recommends planting approximately 350 grass seeds per square meter,

Therefore,

Number of grass seed need = (350×238.35)

Number of grass seed needed = 83422.5 grass seeds
