Write an equation to solve

Patrick now has 6 more than twice the number of baseball cards he had when he started collecting. He now has 98 cards. How many did he have when he started?

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
