Answer:
i think it is 105
Step-by-step explanation:
180-125=55
180-(55+25)=105
*second 180 is triangle's total interior angle
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
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.
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 = 
× 100% = 
×100% = 0.5×100% = 50%
Now,
Average % increase = 
= 
% = 5%
∴ we get
Average percent increase of population per year = 5%
