PLEASE ANSWER I WILL MARK THE BRAINIEST ANSWER :) factorise: X^2 + 10x + 16

Damm [24]

Answer:

(x+2)(x+8)

Step-by-step explanation:

1.)find factors of the third expression(16)that will add up to give the second expression(10)

16=2×8. 10=2+8

2.)substitute those factors inplace of 10

${x}^{2} + 10x + 16$

$x {}^{2} + 2x + 8x + 16$

3.)factorise using grouping method

$( {x}^{2} + 2x) + (8x + 16)$

$x(x + 2) + 8(x + 2)$

$= (x + 2)(x + 8)$

In ΔXYZ, x = 8.3 meters, y = 9 meters, and z = 15 meters. Find the remaining measurements of the triangle, and round your answer

laila [671]

Answer:

The correct answer is B. ∠X = 28.6°, ∠Y = 31.2°, ∠Z = 120.2°

Step-by-step explanation:

Let's recall that for solving a SSS triangle, we :

1. Use the Law of Cosines first to calculate one of the angles

2. Use The Law of Cosines again to find another angle

3. Finally use angles of a triangle add to 180° to find the last angle.

1. Cos x = (9² + 15² - 8.3²/2 * 9 * 15)

Cos x = (81 + 225 - 68.89/270)

Cos x = 0.878

x = Cos ⁻¹ (0.878)

x = 28.6° (rounding to the next tenth)

2. Cos y = (8.3² + 15² - 9²/2 * 8.3 * 15)

Cos y = (68.89 + 225 - 81/249)

Cos y = 0.855

x = Cos ⁻¹ (0.855)

x = 31.2° (rounding to the next tenth)

3. z = 180 - 31.2 - 28.6

z = 120.2°

The correct answer is B. ∠X = 28.6°, ∠Y = 31.2°, ∠Z = 120.2°

Can u explain how u got the answer

Tems11 [23]

Answer:

10 degrees Celsius

Step-by-step explanation:

So, the question is asking for the difference between -8 and 2.

-----------------------------------------------------------------------------------------------------------------

Explanation 1:

2 - (-8) = ?

2 + 8 = ?

10 = ?

-----------------------------------------------------------------------------------------------------------------

Explanation 2:

|2| - 0 = 2

|-8| - 0 = 8

2 + 8 = 10

Will GIVE BRAINLIEst

snow_lady [41]

Answer:

answer will be an=3n+11

Step-by-step explanation:

because when we substitute them...it make sense.

the rule is an=3n+11

lets substitute:

(i).14=3(1)+11

(ii)17=3(2)+11

(iii)20=3(3)+11

(iv)23=3(4)+11

it does make sense....

I hope it will help u....
