Work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100. If your answer is a negative number then this is a percentage decrease.
If the polynomial is of the form x^2+bx+c (ie., no factor in front of the x^2!!) then you can look for numbers that add up to b and multiply to c.
So in this case: what two numbers, when added, give -2 and when multiplied, give 1? A little trial and error gives you -1 and -1.
So the factorization is (x-1)(x-1). This is zero for x=1. There is only one zero.
Answer:
5 1/3
Step-by-step explanation:
2 1/3+(2 2/3) (1 1/8)= 5 1/3
Answer:
DE is equal to 18 feet, then that's already been answered to the 100th of a foot. ... then you would round to 18.23 in order to get to the nearest hundredth foot
Step-by-step explanation:
Step One
Find the Volume in ccs.
V= l*w*h
l =40 mm
w = 25 mm
h = 2 mm
V = 40*35 * 2
V = 2800 mm^3
Step Two
Find the weight
1 mm^3 = 0.0005
2800 mm^3 = x <<<<< answer 1

Cross multiply.
1x = 2800 * 0.0005
x = 1.4 ounces. <<<<< answer 2
