3. You want to put siding on a house that is 18 meters long and 14 meters wide. The walls
are 4 meters high. There are two windows, each measuring 1.5 m by 2 m and a door
that is 1 m wide and 2.5 m high. The siding costs $12.50/m2. How much will it cost to
side the house? (10.3 Meeting) (10.5 Mastery)

Step-by-step explanation:

all we need to do is find the surface area, deduct windows and door areas.

that gives us the m² to be covered, which we have to multiply by $12.50 to get the total price.

what is the problem ? there are only trivial multiplications (with a calculator), additions and subtractions.

the house surface area is like for a box, but we don't care about the top and the bottom. only about the walls.

the "box" is 18 m × 14 m × 4 m.

so, the front and the back walls are each

18m × 4 m = 72 m²

both front and back : 2×72 = 144 m²

each side wall is

14m × 4m = 56 m²

both sides : 2×56 = 112 m²

now for the deductions.

each window is

1.5 × 2 = 3 m²

both windows : 2×3 = 6 m²

the door is

1 × 2.5 = 2.5 m²

so, the total area to "side" is

144 + 112 - 6 - 2.5 = 247.5 m²

to side 247.5 m² it costs

247.5 × 12.5 = $3,093.75

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
