1. Plant Trellis You are building the wood trellis shown in the figure so that you can grow a vine up the side of your home.
Write an expression for the total number of feet of wood needed
to build the trellis. Hint: Write separate expressions for the
number of feet of vertical pieces needed and the number of feet
of horizontal pieces needed. Then find the total number of feet
of wood needed if the trellis is 8 feet tall and 2 feet wide.

i dony know

step-by-step explanation:

ratio is 2 : 9

the answer is three

13.5 : 3

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81

210/22 = 9.55

since he can't take part of a person to the game the answer is 9 people

hope this !
