Answer:
The second one
Step-by-step explanation:
Additive identity is adding 0 to a number
Answer: Assuming that it's already in the standard form - y=mx+b | Your Y-Intercept is going to be -9
Step-by-step explanation:
Using the equation y=mx+b, anything that is in place of the (b) is your Y-Intercept and your slope is (m)
P=2*(L+l)=46
L+l=46:2
L+l=23
(L+l)^2=529
(L^2+l^2)+2l*L=529
D= V L^2+l^2= 17
L^2+l^2=289
so 289+2l*L=529
2l*L=529-289=240
l*L=240:2
A=120
Answer:b=3
Step-by-step explanation:
If a=4b then,
4b-b=9
4(3)-3=9
4x3=12 then - that by 3
So, 12-3=9
Hope that helps
Ex 1 3/2
2 x 1 +3 5
------------ = ----- = 2.5
2 2
first denominator times whatever the whole number is then add that to the nominator than you have an improper fraction
because 3/2 = 1.5 then plus the whole number which is 1.0 = 2.5
