Answer:
Step-by-step explanation:
9) (25-x^2 )(a+2) = (5-x)(5+x)(a+2)
11) 9(v-3)+u^2(3-v)
9(v-3)+u^2( -v+3)
9(v-3)-u^2( v-3)
(9-u^2)(v-3)
(3-u)(3+u)(v-3)
Answer:
x=y
Step-by-step explanation:
-let x be the number of tennis balls and y the number of rackets.
-We divide the number of balls by the number of rackets to find out their ratio of proportionality:

-Hence, for each one tennis ball, there is a tennis racket.
#This is a direct linear relationship and is modeled as graphed in the attachment:
Please send more context as of the "green numbers".
For the multiplication,
i 49 x 10 = 490
490 ÷ 10 = 49
ii 2.3 <span>÷ 10 = 0.23
0.23 x 10 = 2.3
iii 0.034 x 1000 = 34
34 </span><span>÷ 1000 = 0.034
iv 876 </span><span>÷ 100 = 8.76
8.76 x 100 = 876
Hope this helps :)</span>
