Let's call the lesser number x and the other one x+8
Explanation:
The product x⋅(x+8)=240→
Or: x2+8x=240→
We can rework this by subtracting 240 from both sides:
x2+8x−240=0
Now we factor −240 into two factors that add up to 8
After some trying we find 20and−12
The equation turns into
(x+20)(x−12)=0
→x=−20orx=12
So the pairs of numbers will be:
−20and−12 or +12and+20
A prime number is any number divisible by 1 and itself.
61 & 67
Answer:
????????
Step-by-step explanation:
I am pretty positive that it would, the circumference of the tube comes out to roughly 6.28 inches, so thee 8 inch wrapping paper should cover it nicely. Now the sheet of paper is only 2 inches longer than the tube, so the paper will only extend one inch above the tubes edge on either end. the tube has a diameter of 2 inches, so the 1 inch extension all around the tube should fold in and match up quite nicely.
The correct graph is graph 4.
You can find this by looking for recognizable points. This is the easiest way to find composite graphs. In the graph f(x) =|x − 5| + |x − 4| both 5 and 4 yield the answer of 1. You can see that in the examples below:
<span>f(x) =|x − 5| + |x − 4|
</span><span>f(5) =|5 − 5| + |5 − 4|
</span><span>f(5) =|0| + |1|
f(5) = 0 + 1
f(5) = 1
</span><span>f(x) =|x − 5| + |x − 4|
</span><span>f(4) =|4 − 5| + |4 − 4|
</span><span>f(4) =|-1| + |0|
f(4) = 1 + 0
f(4) = 1
Now we can look for graphs that have those two reference points. The 4th graph is the only one that has those. </span>
