Answer:
4/9
or
0.4
Step-by-step explanation:
(2n+4)x(4n+7)
= 8n^2+14x+16n+28
=8n^2+30n+28
that's it :) !!
Answer:
Expand: x² + 11x + 11x + 121
Simplify: x² + 22x + 121
Step-by-step explanation:
To expand this, you can use the FOIL technique:
First terms
Outer terms
Inner terms
Last terms
(x+11)(x+11)
F - x*x = x²
O - x*11 = 11x
I - 11*x = 11x
L - 11*11 = 121
Put these numbers together (expanded) to get:
x² + 11x + 11x + 121
Put the common terms together (simplify) to get:
x² + 22x + 121
Note:
Not sure if you need this info, but (x + 11)(x + 11) is the same as (x + 11)².
The numbers need to be in the order I put them in because you are supposed to place them in order greatest to least degree.
Hope it helps!
(a) The equation is given as Q=45e^1.03t
where e=2.718
Taking t=0 the equation will be :

This will give;

Q=45
okay, so.
it's a rectangle with a nub. We do the area without the nub first. so 8x16 is 128
now, its time for the nub.
6x12-8, that would be 4, so 6x4 is 24+128= 152
So it's B.
Hope i helped Mark brainliest pls
