Answer:
36x^2 + 24x + 4
Explanation:
The perfect square has the following general formula:
(a + b)^2 = a^2 + 2ab + b^2
Now, we will expand the given perfect square based on the above general formula:
(6x + 2)^2 = (6x)^2 + 2(6x*2) + (2)^2
= 36x^2 + 24x + 4
Hope this helps :)
A+b=15----(1)
a*b=54----(2)
(1) a=15-b ----(3)
put(3) in(2)
(15-b)*b=54
15b-b^2=54
b^2-15b+54=0
(b-9)(b-6)=0
so b=9 or b=6
if b=9 then a=15-9=6
if b=6 then a=15-6=9
answer two numbers are 6 and 9
Answer:
7 /24 inch per hour
Step-by-step explanation:
To find the average amount of rain, take the total amount of rain and divide by the time
7 inches / 24 hours
7 /24 inch per hour
3x(2) + 2(2x - 20) = 16 - 2x(2)
6x + 4x - 40 = 16 - 4x
10x - 40 = 16 - 4x
14x - 40 = 16
14x = 56
x = 4
Hope this helps! ;)
You can have 30 and a negative 6. IDK. Hope it can help a bit.
