Answer:
F(a)=2a^2+4a+5
Step-by-step explanation:
Put "a" where "x" is in the function definition:
F(a)=2a^2+4a+5
Answer:
The order of the values from greatest to least are as
Step-by-step explanation:
Negative number goes on decreasing in this way as -1,-2,-3,-4,-5... and so on.
So,-11 > -13 > -21
Here the denominator is same and the numerator is in decreasing order i.e greatest to the least that is 21 > 11 > 3 > -11 > -13 >-21 .Therefore, the order is
Answer:
the answer is 21
Step-by-step explanation:
4x to the power of 2 + 5x
so: 4*1 the power of 2 +5*1
4to power of 2 +5
and 4 to the power of 2 equals 16 (because 4*4=16) and +5
so 16+5=21
6x-3-9x-2
6x-9x = -3x
-3-2 = -5
the the equation is: -3x-5
Answer:
80.6
Step-by-step explanation:
F = 9/5 C + 32
F = (9/5)*27 + 32 Substitute 27 into the equation
F = 243 / 5 + 32 Multiply 9 and 27 together
F = 48.6 + 32 Divide by 5
F = 80.6 Add on 32
A very quick way to do this is to double your centigrade temperature and and 30 which you should be able to do in your head.
2*27 = 54 Add 30
54 + 30 = 84
This quick way will tell you if you get near the right answer.
