178+63+37=278 So if we were ESTIMATING it would be around 280.
I hope that this helps!
<span>Rectangular Prism Volume = length × width × height
</span>
So 4 of those could make the prism:
<span>2 units, 3 units, 6 units
36 units, 1 unit, 1 unit
9 units, 2 units, 2 units
12 units, 3 units, 1 unit
</span>
<span />
The answer is 5.6 because 2+2+4+5+5+6+7+7+8+10=56
and 56/10=5.6
To find the mean<span>, add all the values together and divide by the number of values in the set. The result is your </span>mean<span>!
</span>Hope I helped:)
We were given;
f(x) = x² + x + 2
and
g(x) = 2x + 5
f(g(x)) = f(2x+5)
= (2x+5)²+(2x+5)+2
Expanding brackets gives;
=(2x)²+2(2x)(5) +5²+(2x+5)+2
Simplifying gives;
= 4x² +20x+25+ 2x+5+2
f(g(x))= 4x² +22x +32
