A=(1/2)(h)(B+b)
(6)=(1/2)(h)((2)+(1))
12=h(3)

24 • 24= 576 and 25 • 25= 625
76 • 76= 5,776 and 77 • 77= 5, 929
242 • 242= 58, 564 and 243 • 243= 59, 049√
766 • 766= 586, 756 and 767 • 767=588, 298
( by the way,
I'm squaring it because it's a square.)

3x -5≥ 5x-25
-3x. -3x
-----------------
---> -5 ≥2x -25
+25. +25
---------------------
---->20≥2x
20/2 ≥ 2x/2
----->10≥x, the greatest 'x' can be is 10.
Box 1 : 3 pencils + 7 pens = total of 10
probability of picking a pen is 7/10
box 2 : 3 pencils + 3 crayons = total of 6
probability of picking a crayon is 3/6 which reduces to 1/2
probability of picking both is (7/10 * 1/2) = 7/20 <==
Answer: -3
Step-by-step explanation:
If you plug in the numbers, the equation would look like: 2+2(-2.5)
Multiply 2 by -2.5 and you'll get -5 as your product. Add 2 and -5 together to get the sum of -3.
