First divide, then add

6 ÷ 2 = 3

42 + 3 = 45

It's not 7, 11, or 19. and I'm 100 % positive the answer is 45

Answer 2

Answer:

Answer:

I think you meant 4^2 or 4 to the second power so the answer is 19. Ijust took the quiz and got all right.

Which of the following represents the measure of all angles coterminal with 418° angle?

Answers

The correct answer is:

58+360n, for any integer n.

Explanation:

412° is more than 360°, which is a full circle. To find the smallest angle that is coterminal with 412°, we subtract 360° from it:
412-360 = 58°

This means that 58° is the smallest coterminal angle with 412°.

Every whole circle added on to this will also be coterminal with it. Again, a whole circle is 360°; this means that every 360° increment that is added to 58° will be coterminal with it.

To represent multiples of 360, we write 360n. Adding this to our original angle, we have 58+360n.

This works for positive and negative numbers; for example, if you use n = -1:

58+360(-1) = 58-360 = -302

Graphing this angle, we would go counterclockwise from the positive x-axis; we would land at 58°, so it would still be coterminal with 412°.

418° is the same angle as 360° + 58° .

And then, if you add any whole number of 360s onto it,
you get the same angle again.

So it's 58+360n with n=any whole number
(n=0 doesn't work, so it's not 'integer'. '0' is an integer.)

F(x)=3x+1 and g(x)=x^2-6 find (f+g)(x)

Answers

Answer is x^2 + 3x - 5 As, f(x) = 3x + 1 And g(x) = x^2 - 6 We have to find (f+g)(x) For that we should know (f+g)(x) = f(x) + g(x) So it will become = (3x + 1) + (x^2 - 6) = 3x + 1 + x^2 - 6 = x^2 + 3x - 5

Answer:

It would be x^2 + 3x - 5.

Step-by-step explanation:

Solve each question for X , y=-9+x^2

Answers

so basically you want to isolate only one of the variable on one side so
y=-9+x^2
add 9 to both sides
y+9=x^2
square root both sides
$√(y+9)=x$

x= $√(y+9)$

y = -9 + x^2
y + 9 = -9 + 9 + x^2
y + 9 = x^2
√y+9 = √x^2
√y+9 = x
x = √y+9

√ is the square root symbol

Find the common difference for the sequence shown. 56, 49, 42, 35, ...
a. -12 b .-7
c. 7

Answers

Answer:

Common difference is -7.

Step-by-step explanation:

Given : sequence 56, 49, 42, 35, ...

To find : Find the common difference.

Solution : We have given that 56, 49, 42, 35, ...

By the common difference of an arithmetic sequence is:

d = $a_(2) -a_(1)$

Where, $a_(1)$ is the first term and $a_(1)$ is the second term.

Then common difference = 49 -56

= -7 .

Therefore,b) common difference is -7.

b. -7
This will be common difference of this sequence
it is such an easiest question

The triangle is isosceles. It also has two 45 degree angles. That means the sides are "x" and the hypotenuse is sqrt(2)*x. If you do the math, the answer is 8.485
