The scale is 2:3 so it would be like this
2:3
4:6
8:16
If you mean the "x" is multiply, then your answer is 35x9+14x8+56x7−30x2−12x−48
Explanation:
=(5x2+2x+8)(7x7+−6)
=(5x2)(7x7)+(5x2)(−6)+(2x)(7x7)+(2x)(−6)+(8)(7x7)+(8)(−6)
=35x9−30x2+14x8−12x+56x7−48
=35x9+14x8+56x7−30x2−12x−48
Answer:
6a
Step-by-step explanation:
AB = √[(3a - -3a)² + (0)²]
⇒ AB = √[(3a + 3a)² + (0)²]
⇒ AB = √[(6a)² + (0)²]
Answer:
<h2>
</h2>
Step-by-step explanation:
-4÷2 = -2
8÷(-4) = -2
-16÷8 = -2
So this is a geometric sequence with the first term of 2 and a common ratio of -2
the nth term of a geometric sequence:
Therefore:
Your question seem to me non-understandable. Are they adding up together ?
or multiplying ?
