So similar triangles have the same ratio 10/8=1.25 therefore 15/12=1.25 so DF=12M
Step-by-step explanation:

So there's no answer, because D must be equal or more than 0.
Given that the series is given by:
an=5an-1+2
where:
a1=3
then the other terms of the sequence will be:
a2=5a1+2
a2=5*3+2=17
a3=5a2+2
a3=5(17)+2
a3=87
a4=5a3+2
a4=5(87)+2
a4=437
a5=5a4+2
a5=(5*437+2)
a5=2187
hence the sequence will be:
<span>3, 17, 87, 437, 2187
</span>
Answer: <span>a) {3, 17, 87, 437, 2187}</span>
Answer:
<h2>The number is 75</h2>
Step-by-step explanation:
Let the number be x
A third of a number is written as

A third of a number minus 8 is written as

The result is 17
We have

<u>Add 8 to both sides of the equation</u>
That's

<u>Multiply through by 3 to eliminate the fraction</u>
That's

<h3>The number is 75</h3>
