Answer:

Final answer is 3x^2-4x+15

Step-by-step explanation:

we have been given an expression (5x^2+3)-(2x^2+4x-12).

Now we need to subtract them.

We can subtract like terms only that has same variable with same exponent.

(5x^2+3)-(2x^2+4x-12)

=5x^2+3-2x^2-4x+12

=5x^2-2x^2-4x+3+12

=(5-2)x^2-4x+(3+12)

=(3)x^2-4x+(15)

=3x^2-4x+15

Hence final answer is 3x^2-4x+15

Answer:

(5x^2+3)-(2x^2+4x-12) = 3x²-4x+15.

Step-by-step explanation:

We have given the expression:

(5x²+3)-(2x²+4x-12)

We have to subtract.

(5x²+3)-(2x²+4x-12)

5x²+3-2x²-4x+12

5x²-2x²-4x+3+12

3x²-4x+15

3x²-4x+15 is the answer.

Find the length of BC
bazaltina [42]

Answer:

BC = 19.78

Step-by-step explanation:

using sin(x) rule

sin(54)= 16/BC

sin(54)=0.80

∴0.80=16/BC  (divied both side by 0.80)

BC=16/0.80 =19.78

What is the equation of the line that passes through the point (6, 3) and has a slope of -2?
tekilochka [14]

We know the equation of a line is y=mx+b. We know the slope (m) is -2 and all we need is the intercept (b).

Since we know one point, we can plug in 6 for x and 3 for y (along with -2 for m) in our equation and then solve for b.

3= -2*6 + b

3= -12 + b

15 = b

Since we now know the intercept we can now write our equation:

y= -2x + 15
