9+3x
Step-by-step explanation:
3 (3+x)
Distribute
3*3 + 3*x
9+3x
the answer is 4.5 ft
Step-by-step explanation:
Step-by-step explanation:
Given that the two fugures in the question above are similar, it means they have the same shape, even though they are if different sizes, the ratio of their corresponding sides are proportional. Thus,
18/x = 8/2
Let's solve for x as required.
We have,
18/x = 8/2
=>Cross multiply:
18 × 2 = 8 × x
36 = 8x
=>Divide both sides by 8
36/8 = x
4.5 = x
x = 4.5 ft
It is D because us the given equation all you do is plug in the x values given on the chart
4x^5 + 3x + 1...the ^5 makes it a fifth degree....and the leading coefficient is 4
