Could someone please help me asap? Thanks in advance! :)
Elden [556K]

Answer:

A

Step-by-step explanation:

the standard form of a quadratic equation is

ax² + bx + c = 0 : a ≠ 0

obtain (5 + x)(5 - x) = 7 in this form by expanding the factors

25 - x ² = 7 ( subtract 7 from both sides )

18 - x² = 0 ( multiply through by - 1 )

x² - 18 = 0 ← in standard form

with a = 1, b= 0 and c = - 18 → A

Jack is 13 years younger than his older brother, Tyler. Their Dad is twice Tyler's age. The sum of their ages now is 91. Find Ja
grin007 [14]

Answer:

13 years old

Step-by-step explanation:

So to solve this we use a system of equations. Let's use "j" to represent Jack, "t" to represent Tyler, and "d" to represent the dad. Set the system up and it will look something like this:

j = t - 13 (Jack is 13 years younger than Tyler)

d = 2t (Dad is twice Tyler's age)

d + j + t = 91 (The sum of the ages is 91)

And then solve, I solved by isolating the "j" variable on the last equation, giving us j = 91 - t - d, then plugged that into the first equation, giving us 91 - t - d = t - 13, and got d = 104 - 2t. Then I plug that into d = 2t, giving us 104 - 2t = 2t, and solve for t. T is 26, meaning Tyler is 26 years old, and then I just subtract 13 from that, giving us 13 years old.

And finally, I obviously checked my answer, because now we know dad is 52, and I got 91.

4. Where in the ocean does the water droplet need to be located in order to evaporate?
weeeeeb [17]

Answer:

C or D most likely C

Step-by-step explanation:

Definitely not A or B they don’t matter or make sense.. C makes more sense because it’s directly hit with heat needed to evaporate, for D to be lower it’ll take longer if at all to evaporate because it’s colder closer to the sea floor

Sauron [17]

Answer:

15.2

{c }^{2}  =  {a}^{2}    +  {b}^{2}  \:  \\  {c}^{2}  ={6}^{2}  +  {14}^{2}  \\  {c}^{2}  = 36 + 196  \\  {c}^{2}  = 232 \\  \sqrt{c }  =  \sqrt{232}  \\ c = 15.23154621
