Answer:
see below
Step-by-step explanation:
3x^2 + 17x +10 =0
(3x+ ) ( x+ ) =0
We need to factor 10 = 2*5 or 1*10
They are positive since we have all positive terms
3*5 = 15+2 = 17
The 5 needs to multiply the 3 so it goes on the outside
(3x+ ) ( x+ 5 ) =0
That leaves the 2 on the inside
(3x+ 2 ) ( x+ 5 ) =0
Using the zero product property
3x+2 =0 x+5=0
3x = -2 x=-5
x = -2/3 x = -5
Answer:
36 - 18 longest side = 18
Step-by-step explanation: This would mean both sides are 18.
Answer:
You have 1.07 acres in this building lot and you can only build 2 houses.
Step-by-step explanation:
You are looking at a 260 foot by 180 foot building lot to subdivide and build two houses.
We are given that 1 acre = 43,560 square feet.
In this building plot (260 foot by 180 foot), the area is:
260 * 180 = 46,800 square feet
Hence, the number of acres we have in this lot is:

Since your town requires 1/2 acre to build a house, the number of houses that you can build on it will be:

Since the number of houses can only be whole number, we approximate to nearest whole number ≅ 2 houses.
You have 1.07 acres in this building lot and you can only build 2 houses.
So I did 5/2 and I got 2.5
5 divided by 2 = 2.5
Not 100% sure if I'm right though
