Factorise
x^2+18x+80

Answers

Answer:

(x + 10)(x + 8)

Step-by-step explanation:

Given

x² + 18x + 80

Consider the factors of the constant term (+ 80) which sum to give the coefficient of the x- term (+ 18)

The factors are + 10 and + 8 , since

10 × 8 = + 80 and 10 + 8 = + 18 , then

x² + 18x + 80 = (x + 10)(x + 8) ← in factored form

What question do you ask a basketball player from Indiana?

Answer:

  WHOOSIER COACH

Step-by-step explanation:

Linear pairs are supplementary. Vertical angles are congruent. An angle is the sum of its parts.

(a) C: supplementary to 138°, 180° -138° = 42°

(b) O: congruent to 138°

(c) R: supplementary to 32°, 180°-32° = 148°

(d) H: congruent to 32°

(e) S: complementary to 28°, 90° -28° = 62°

(f) O: supplementary to 122°, 180° -122° = 58°

(g) W: congruent to 122°

(h) C: supplementary to 28°, 180° -28° = 152°

(i) I: supplementary to 60°, 180° -60° = 120°

(∠TSW) E: supplementary to a right angle: 180° -90° = 90°

(∠TSU) O: half the complement of 20°, (90° -20°)/2 = 35°

(∠USW) H: complement of ∠TSU, 90° -35° = 55°

(∠RSV) A: supplement of ∠VSW = 180° -35° = 145°

__

The desired order of the letters corresponds to the sequence of angles ...

  122°, 55°, 58°, 35°, 62°, 120°, 90°, 148°, 71°, 152°, 138°, 145°, 42°, 32°

Answers

Answer:1/8

Step-by-step explanation:

If we divide both the top and the bottom by 5 since we know that 125 is a multiple of 5, we get 25/200. Divide both by 5 again to get 5/40 we then simplify to get 1/8.

Answers

Answer:

Step-by-step explanation:

Let the number of users be x

x + 33% of x = 7.5 million

12 - 3 = 9

Answer:

p=-2

Step-by-step explanation:

Move the -3 to the other side by adding 3 on both sides:

-6p-3+3=9+3

The equation now looks like this:

-6p=12

Divide -6 on both sides:

-6p/-6=12/-6

The equation now looks like this:

p=-2 which is the answer
