Answer:
$5?
Step-by-step explanation:
3 x 4=12
12 is a dosen
1.25 x 4=5
Answer:
X^2+7x+4
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
In this technique, if we have to factorise an expression like ax2+bx+c, we need to think of 2 numbers such that:
N1⋅N2=a⋅c=1⋅−12=−12
AND
N1+N2=b=−1
After trying out a few numbers we get N1=3 and N2=−4
3⋅−4=−12, and 3+(−4)=−1
x2−x−12=x2−4x+3x−12
x(x−4)+3(x−4)=0
(x+3)(x−4)=0
Now we equate the factors to zero.
x+3=0,x=−3
x−4=0,x=4
The median is 19.5. 16+23 is 39. 39/2 is 19.5
K=5
if you add 5 to f(x) it will move up five and become g(x)
