Answer:
3y √21 + 2 y√15
Step-by-step explanation:
To simply, we open up the bracket
We have this as;
√(189y^2) + √60y
= 3y √21 + 2 y√15
Answer:
80
Step-by-step explanation:
0, 3, 8, 15, 24, <u>35,</u> <u>48,</u> <u>63,</u> <u>80</u> which is the nth term
first step you have to find how many steps the sequence was going with.
examples= from 0 to 3 the steps were 3
=from 3 to 8 the steps were 5
= from 8 to 15 the steps were 7
you will recognize that the steps the sequence is going with is odd numbers.
so you will use the odd numbers until you find what you need. which leads you to 80 which is the nth number in the sequence.
Answer:
The formula y = mx + b sometimes appears with
different symbols.
For example, instead of x, we could use the
letter C. Instead of y, we could use the letter F.
Then the equation becomes
F = mC + b.
All temperature scales are related by linear
equations. For example, the temperature in
degrees Fahrenheit is a linear function of degrees Celsius.
Water freezes at: 0°C, 32°F
Water Boils at: 100°C, 212°F

Answer:
1:2, 2:4, 3:6
Step-by-step explanation:
If you times 1:2 by 2, you get 2:4. If you times 1:2 by 3, you get 3:6.
You have to multiply each individual number in the ratio.
