Have a good day :)
224 divided by 7...
70/7 = 10
70/7 = 10
70/7 = 10
14/7 = 2
so ur answer is 32
3(9)+2(6)=
multiply 3•9=27
multiply 2•6=12
27+12=39
Answer:
f(x) = (x+5)(x-1)(x-3)
Step-by-step explanation:
From the graph, we have that the function intercepts the x-axis at the points x = -5, 1,3
From here, we have
x = -5
x = 1
x = 3
So we have the factors as;
x + 5, x - 1 , x - 3
So what this mean is that we have the function as;
f(x) = (x+5)(x-1)(x-3)
Answer:
4/9
Step-by-step explanation:
0.4444... can be written as a geometric series with first term 0.4 and common ratio 0.1. Each new digit is 0.1 times the previous digit.
0.4
Then 0.4444... = ------------ = 0.4/0.9 = 4/9
1 - 0.1
You may check this result by dividing 4 by 9 on a calculator.
