The first step in the process for factoring the trinomial x2-3x - 40
Alexxx [7]
We need two numbers that when multiplied will give you -40 and when added will give you -3:
(x+5) (x-8) this is your answer. And you want to know the process Here it goes. And attached is a chart I made you so you can visually see what this process is telling you:
1) identify a,b, and c in the trinomial ax^2 + bx+c (in your case it's 1x^2-3x-40= x^2-3x-40)
2) write down all factor pairs of c (numbers that multiplied produce -40)
3) identify which factor pair from the previous step sums up to b
4) Substitute factor pairs into two binomials

makvit [3.9K]

Answer:

Width = (x + 8) inches.

Step-by-step explanation:

The  area of the quilt is the length times the width and if we know the area and the length we can find the width by area / length.

Area = x^2 + 18x + 80 = (x + 10)(x + 8) - now we know that the length is (x + 10) so the width must be (x + 8) inches.

Let me know if you require more explanation.

The population of the town increased from 175000 to 262500 in a decade. What is the average percent increase of population per y
Alenkinab [10]

Answer:

5%

Step-by-step explanation:

As given,

The population of the town increased from 175000 to 262500 in a decade.

⇒ In 10 years , population increased from 175000 to 262500

⇒% increase = \frac{262500 - 175000}{175000}× 100% = \frac{87500}{175000}×100% = 0.5×100% = 50%

Now,

Average % increase = \frac{percent increase}{Total years} = \frac{50}{10}% = 5%

∴ we get

Average percent increase of population per year = 5%
