5:7 (pencils to pens)
7/12 chance that a pen from the first box will be selected.
4:4 (colour pencils to crayons)
4/8 = 1/2 chance that a crayon from the second box will be selected.
The probability of picking both:
7/12 * 1/2 = 8/24 = 1/3
The answer is 12 5/18 hope it helps
1. ( t + 8) (t - 6) t = -8 and 6
2. prime
3. (t - 16) (t + 3) t = 16 and -3
4. prime
5. (t + 15) (t - 2) t = -15 and 2
answer:
52
step-by-step explanation:
- we can use the 45-45-90 triangle theorem for this: x, x, x

this is because this is a square
- squares have two sides of the same length, and the diagonal is different
- the x's stand for the sides, whereas the x
stands for the diagonal
x
= 26
x = 13
- now multiply this by 4 because this is the length of one of the sides of the square. in order to find the perimeter we have to either add this four times or multiply by 4
13
X 4 = 52
