Answer:

The first four terms are;

w(x)= 4 + 2x² - ⁵/₆x⁴+ ¹¹/₃₆x⁶ +......

Step-by-step Explanation:

This is the interpretation of the question

Question is in png pls some1 help !
Reika [66]

Answer:

Triangle x = 30. Pentagon x = 50

Step-by-step explanation:

For the triangle,

Find the angle which is beside x in the triangle,

let's name that angle y, so 55 + 55 + y = 180 ( we find 55 by subtracting both angles 125 from 180)

110 + y = 180

Y = 180 - 110

y = 70

Now that we have find Y, we can easily find x by subtracting 70 from 180 which would be, 70 + X = 180

x = 180 - 70

x = 30

For the pentagon,

Again find the angle which is beside x in the pentagon,

let's name that y again, 90 + 120( by subtracting 60 from 180) + 110( by subtracting 70 from 180)  + 90 + y = 540

210 + 200 + y = 540

410 + y = 540

y = 540 - 410

y = 130

Now that we have find y, we can easily find x by subtracting 130 from 180 which would be, 130 + x = 180

x = 180 - 130

x = 50

Hope this helps!

Kristen gets home from work at 5:34 p.m. Kristen's dinner is ready at 5:51 p.m.
bazaltina [42]

Answer:

1,020 seconds

Step-by-step explanation:

we know that

To find out how many seconds after Kristen gets home is her dinner ready, subtract the time Kristen gets home from the time Kristen's dinner is ready

so

5:51 p.m-5:34 p.m=17 min

Remember that

1\ min=60\ sec

Convert minutes to seconds

17\ min=17(60)=1,020\ sec
