2x^2+4x+2
Carry the 2 over to the 3 behind the 4 and multiply so 2times2 is 4. So i new equation is.
X^2+4x+4
Now you have to find the factors of 4 which is 1,4 and 2,2
So now you have to see which one adds up to 4 so 1+4 is 5 so cross that out and 2+2=4.
So the two number is 2 and 2 now you have to bring down the x^2 and the signs.
(X+2) (X+2) and thats your answer

See the picture to better understand the problem

we know that
in the triangle ABC
∠A+∠B+∠C=180°
∠C=180-(86+69)-----> ∠C=25°
Applying the law of sines
b/sin B=c/sin C------> b=c*sin B/sin C-----> b=82*sin 69/sin 25
b=181.14 ft

the answer is
181.14 ft

8x+21=3 need the answer please
GarryVolchara [31]

Answer:

x=-\frac{9}{4}

Step-by-step explanation:

<u>Step 1:  Subtract 21 from both sides</u>

8x + 21 = 3

8x + 21 - 21 = 3 - 21

8x = -18

<u>Step 2:  Divide 8 from both sides</u>

8x = -18

\frac{8x}{8}=-\frac{18}{8}

x=-\frac{9}{4}

Answer:  x=-\frac{9}{4}
