Express (x + 10)^2 as a trinomial in standard form.

Mathematics
1 answer:
nydimaria [60]3 years ago
5 0

Answer:

x2-20x+100

Step-by-step explanation:

You have to factor the expression in order to get your answer

Do this by expanding out the expression: (x-10)(x-10) Then factor by multiplying each of the components! Use the FOIL acronym to help you. FOIL stands for First, Outer, Inner, Last. Meaning multiply the first numbers of the expressions together, then the outers, then the inner two numbers, then the last two numbers of the expression.

Multiply x and x to get  , multiply x and -10 to get -10x, multiply -10 and x to get -10x, multiply -10 and -10 to get 100. Add them all together:  . Then combine like terms

A large grandfather clock strikes its bell once at 1:00, twice at 2:00, three times at 3:00, etcetera. what is the total number
erastovalidia [21]
There is a formula for adding consecutive integers.
sum = (n * (n+1)) / 2
for summing 1 through 12 it is
sum = (12 * 13) / 2 = 156/2 = 78
The clock goes through two "12-hour cycles" in a day, so the answer is 2 * 78 or 156 times.

Option B is correct option.

Step-by-step explanation:

We need to identify equations written in factored form.

Factored form: A factored form of expression is an expression broken down into a product of its factors.

In the given options A, C and D we don't have product of factors.

Only option B consists of product of factors.

So, Option B is correct option.

What are the dimensions of the lightest​ open-top right circular cylindrical can that will hold a volume of 2744 cmcubed3​?
nata0808 [166]

Answer:

r=2.808cm    h = 100cm

then we get volume of cylinder that is 2744 As explained below

Step-by-step explanation:

Volume of cylinder = πr²h

Surface area of cylinder = 2πrh +πr²                                (1)

h= 2744 /πr²

put value oh h in equation (1)

Area =[2πr] 2744 /πr²

        =[5488/r +πr²]

dA/dx=0                                      

i.e     2πr=5488/r²

Solving this r.r= ∛5488/2π

                       =2.808

taking second derivation we get 100
