Answer:

18

Step-by-step explanation:

Important things to know:

“PEMDAS” is parenthesis, exponents, multiplication, division, addition, subtraction

equation: \frac{2(x^{2}+18) }{x}

If x = 3, than

→  \frac{2((3)^{2}+18) }{3}

after plugging in 3, we solve inside the parenthesis

3 to the power of 2 is 3 x 3 = 9

→    \frac{2(9 + 18)}{3}

than you add the remaining things in the parenthesis where 9 + 18 = 27

→    \frac{2(27)}{3}

multiply 27 by 2 = 54

→    \frac{54}{3} = 18

divided 54 by 3 to get 18 as your final answer

What is 7 times as much as the sum of 1/3 + 4/5
riadik2000 [5.3K]
Lets write the problem info into an equation and solve step by step:
7(1/3 + 4/5)
the minimum common multiple of 3 and 5 is 15, so we multiply and divide the fractions by a proper number to convert them to be divided by 15 so is easier to add them:
<span>(1/3)(5/5) = (1*5)/(3*5) = 5/15
(4/5)(3/3) = (4*3)/(5*3) = 12/15
</span>so we substitute in the original equation:
7(1/3 + 4/5<span>)
</span>= 7(5/15 + 12/15<span>)
= 7(17/15)
= (7*17)/15
= 119/15</span>

Find the perimeter of the shape. (Answer choice In pic)
Lana71 [14]
Answer: 49.2 cm



Explanation: I don’t know how to explain it without a visual so I hope you end up figuring it out! All I can say is: use Pythagorean’s theorem for that triangle to the left (if you know what I mean) to find the hypotenuse and then add all the sides up!

Have a great day!
