6 0

Answer:

3x²(4x-3)

Step by step explanation:

Factorise 12x³-9x²

first, find the HCF of the terms.

the HCF is 3x²

Then you can use the HCF to multiply all terms, each divided by the HCF.

3x²(12x³/3x²-9x²/3x²)

Dividing, we'll have

Aaron want to buy sod for his backyard. What is the amount of area he will need to cover?
Lerok [7]

Answer:

(16 + 8√3) in²

Step-by-step explanation:

The ratio of side dimensions for a 30°-60°-90° triangle are 1 : √3 : 2. If we call the horizontal dimension of the triangle its base, then its height (vertical dimension) will be √3×4 in. Of course the area of the triangle is ...

... A = (1/2)bh = (1/2)(4 in)(4√3 in) = 8√3 in²

The total sod area is the sum of the square area (16 in²) and the triangle area, so is ...

... area to cover = (16 +8√3) in²

_____

<em>Comment on problem dimensions</em>

The area involved here is not much larger than the size of your hand. It would make more sense for the dimensions to be in feet or yards or meters, rather than inches.

Find four consecutive multiples of 5 whose sum is 90
STatiana [176]

Answer:

15, 20, 25, 30

Step-by-step explanation:

If want to find the first multiple, we could actually use the equation: x + (x+5) + (x+5+5) + (x+5+5+5) = 90. After simplifying this term, we would get 4x+30 = 90 which then transforms into 4x=60 which simplifys to x = 15. Plug 15 into the original equation, and you would get the multiples 15 + 20 + 25 + 30 = 90.
