Answer:

2(4+x)

Step-by-step explanation:

"Twice the sum of" tells us it will be the equation times two

"the sum of four and a number" is easy, thats 4 + x

The second number is x because the number is not specified so we need a place holder, x in this case, to tell us that the number is not given.

All this put together = twice the sum of four and a number, or 2(4+x)

Answer:

68469.44

Multiplication is commutative so can be multiplied anyway

(2.0× 109)(3.02×104)

2.0 can be written as ( 20÷ 10) and 3.02 can be written as (302÷ 100)

(2× 109){(3.02÷ 100)× 104]

(218)(7852÷ 25)

Answer

15% of 30

 $30 \times 15\% \\ 30 \times \frac{15}{100} \\ = 4.5$ 

30% of 45

 $45 \times 30\% \\ 45 \times \frac{30}{100} \\ = 13.5$ 

60% of 7

 $7 \times 60\% \\ 7 \times \frac{60}{100} \\ = 4.2$ 

23% of 20

 $20 \times 23\% \\ 20 \times \frac{23}{100} \\ = 4.6$ 

Hope this helps you:-)

Delicious77 [7]

We are given the statement that the strength, S, of a beam of width w andheight h is proportional to wh2. hence using k as the proportionality constant, the equation is S = k wh2. the exact width and height can be determined by applying optimization to the problem. optimization is taking the first derivative of an equation and equating then to zero
