She can add 35 and 9 which equals 44
Answer:
Step-by-step explanation:
1. Cut six desired measures of string to properly wrap and tied around each end of the three sticks
2. Once fastened, bring two of the sticks together making one the bottom (base) and the other a side (angle).
3.Cut a tiny piece of rope to interlock with the rope you already have tied on the ends.
4.Tie the ends together with the new cut of string and make your desired angle as you tighten it.
5. Mirror Step 4 for the other end of the bottom stick (base), while most importantly mirroring the desired angle of step 4.
This should give you a proper equilateral triangle made out of sticks and string or anything of these two materials.
Answer:
6. (a-4)(a+9)
7. (3p+4)(p-2)
8. Will explain below.
9. (5b+4)(5b-4)
Step-by-step explanation:
HELLOOO IM BACK
6. -4*9 = -36 (the variable), 9-4 = 5 (a) , so a^2 +5a - 36 is fulfilled.
7. 4*-2 = -8, 4-2 = 2, so 3p^2 - 2p - 8 is fulfilled.
9. 25b^2 = (5b)^2
16 = 4^2
Using the difference of squares formula, a^2-b^2= (a+b)(a-b)
Since volunteers can be of any sexe (no precision given in your problem), then we can consider the question as how many group of 6 we can make with 12 persons:
It's a combination of 6 chosen among 12
¹²C₆ = (12!)/(6!).(12-6!)
²C₆ = (12!)/(6!).(6!)<span>
</span>¹²C<span>₆</span> = 924 Ways
