Factor x2 + 11x + 30.

Mathematics
1 answer:
andrey2020 [161]2 years ago
6 0

Answer:

  (x +5)(x +6)

Step-by-step explanation:

You're looking for two factors of 30 that total 11.

  30 = 1×30 = 2×15 = 3×10 = 5×6

5+6 = 11, so those are the numbers you want in the binomial factors.

  x^2 +11x +30 = (x +5)(x +6)

_____

<em>Additional comment</em>

You will notice that ...

  (x +a)(x +b) = x^2 +(a+b)x +ab

The constant is the product of the factor constants, and the x-coefficient is their sum.

The processing speed of a certain computer is 10¹¹ instructions per second. Another computer has a processing speed that is 10³
Mashcka [7]
“Times as fast” means you need to multiply the original speed (10^11) by how many times faster the faster processor works:

10^11 instructions/second • 10^3 faster = 10^14 instructions/second

The key is “___ times as fast”.

Find the distance between points C(-1, -1) and D(6, 2) to the nearest tenth.
givi [52]

Answer:

≈ 7.6

Step-by-step explanation:

Calculate the distance using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 1, - 1) and (x₂, y₂ ) = (6, 2)

d = \sqrt{(6+1)^2+(2+1)^2}

  = \sqrt{7^2+3^2}

  = \sqrt{49+9}

  = \sqrt{58} ≈ 7.6 ( to the nearest tenth )
