Answer:
(12-7x)
Step-by-step explanation:
144 − 49x²
by observation, we can see that 144 = 12² and 49 = 7²
hence we can rewrite the equation
144 − 49x²
= 12² - 7²x²
= 12² - (7x)²
recall that the expression x² - y² = (x+y)(x-y)
hence,
12² - (7x)²
= (12 + 7x)(12-7x)
(12-7x) appears in the expression above, hence 12 -7x is a factor
At the start you will start with $7 and $7.60 there is a simple way and a more complex process. The simple way is using the formula of y=mx+b so y=.8x+7 and the other way is just too add .8 to 7 and .7 to 7.6 and keep doing that till you get the answer. The answer is 7, seven topping have to be added to make them the same price.
Answer:
8y
Step-by-step explanation:
Product means multiply
8*y
8y
Answer:
9 arms
Step-by-step explanation:
6 eyes = 2 eyes three times (3 x 2), so three arms 3 times (3 x 3) = 9
Answer:
14.6
Step-by-step explanation:
It is given that,
The average weight of the top 5 fish caught at a fishing tournament was 12.3 pounds. From the attached figure, the weight of 5 fish are given. We need to find the weight of Wayne S. fish.
Average = sum of terms/no of terms
Let the weight of Wayne S. is x. So,
Here the sum of terms is x+12.8+12.6+11.8+9.7 and the number of terms is 5.
So, the weight of the heaviest fish is 14.6.
