Answer:
56
Step-by-step explanation:
4*7*2 is 56
f(x) = 3x²
g(x) = 4x³ + 1
f(g(x)) = 3.(4x³ + 1)²
As we know
(a + b)² = a² + 2.a.b + b²
So,
(4x³ + 1) = (4x³)² + 2.4x³.1 + 1² = 
f(g(x)) = 3.(
)
The degree is the maximum exponent, so, 6.
Answer:

Step-by-step explanation:
Because the initial temperature is 40 degrees and it increases by 10, add the two values together to get the final temperature.
40 + 10 = 50
Therefore, the final answer is 50 degrees.
Solution: The needed answer for first blank is 1 and the needed a for second blank is 1.
Explanation:
The given equation is
.
The form of perfect square is
.
The given equation can be written as
.
To make the perfect square we can add or subtract
in the given equation. Where, a is coefficient of
and b is coefficient of x. In the parenthesis the coefficient of
is 1 and coefficient of x is 2.

So, the given equation is written as 

Therefore, the needed answer for first blank is 1 and the needed a for second blank is 1.
