Answer:
3
Step-by-step explanation:
((7x-4)^2) - (7x-4)(7x-4) + 3
(7x-4)(7x-4) is 7x-4^2
So its (7x-4)^2 - (7x-4)^2 + 3
(7x-4)^2 cancel out.
Answer is 3
Answer:
About 11 cups of rice
Step-by-step explanation:
We have 2 1/2 kg of rice. Or we can say 2.5 kg of rice.
Since we want cups and cups is given with ounces (oz), we need to convert the kg amount to ounce amount, first.
We know:
1 kg = 35.274 oz
So, 2.5 kg is:
2.5 * 35.274 = 88.185 oz
Since 1 cup is 8 oz, 88.185 oz is how many cup??
That would be:
88.185/8 = 11.02 cups
Rounded, that is about 11 cups of rice

Answer:
Shorts = 112 and t shirts = 165
Step-by-step explanation:
Let S = shorts
Let T = t shirts
T + S = 277
$2T + $3S = $656
-2(T + S) = 277 so -2T -2S = -544
2T + 3S = 656 so 2T + 3S = 656
------------------------
SO: (subtract T's cancel out) 1S = 112
divide by 1 so S = 112
Plug S into the top equation: T + s = 277 T + 112 = 277 so T = 165
