√ab=(√a)(√b)
find perfect squares
√50=(√25)(√2)=5√2
answer is A
Well 75x12=900 so 900 divided by 40 is 22.5 so 22 teachers can have 40 chalks but the principal needs to order another 20 :)
Answer:
m=6
Step-by-step explanation:
For this figure to be a parallelogram, the sides must be the same length
4m+2 = 3m+8
Subtract 3m from each side
4m+2-3m = 3m+8-3m
m+2 =8
Subtract 2 from each side
m+2-2 =8-2
m=6
Both angles are congruent and since opposite angles of a trapezoid = 180, s and t equal 108.
