Answer:
A number is divisible by 10 if it has a zero in ones place.
Step-by-step explanation:
- We know that 10= 2 x 5 .
- So to be divisible by 10 we have to be divisible by both 2 and 5
- As we know ,Numbers divisible by 2 are even numbers and numbers divisible by 5 if it has a zero or a five in ones place .
- From that, we have A number is divisible by 10 if <u>it has a zero in ones place.</u>
First thing you must do is square root both sides. This gives you:
1/3y + 2 = √121 which becomes 1/3y + 2 = 11 and 1/3y + 2 = - 11
This is because both 11 and - 11 when squared are equal to 121. So we must solve for both to find the solutions.
1/3y + 2 = 11
Subtract 2 from both sides to get 1/3y = 9
Now multiply both sides by 3 to isolate the variable y
3(1/3y) = 9(3) which becomes y = 27.
Now for the other equation 1/3y + 2 = - 11
Again, subtract 2 from both sides to get 1/3y = - 13
And multiply by 3 to isolate the variable y
3(1/3y) = - 13(3) which becomes y = - 39
Your answer: y = - 39, 27
It is 9 because you need to triple 3 so 3x3 is 9
Answer:
4×(x² - 4x + 2)
Step-by-step explanation:
4x2 - 16x + 8 = 4×x² - 4×4×x + 4×2 = 4×(x² - 4×x + 2)
3 because the heart color is switched around.
