−6y2(−13x2y5) please help, I'm supposed to FULLY simplify this

Answers

Answer 1
Answer:

You would multiply the two terms which are -6y^2 and -13x^2*y^5.

Multiplying -6 by -13 yields 78, which will be the new coefficient.

Since there is only the x^2 from the second term, that remains the same. However, there are two y values that we can multiply together: y^2 and y^5. y^2 * y^5 = y^(2 + 5) = y^7.

Therefore, your answer is 78x^2*y^7.

Please help!The area of a rectangle is 240 square meters. Find the length and the width of the rectangle, if the length is 8 meters longer than the width.

Answers

Let the width=x mtr

So the length will be x+8 mtr

so the are of the rectangle will be=x(x+8)=240

x²+8x=240

x²+8x-240=0

x²+20x-12x-240=0

x(x+20)-12(x+20)=0

(x+20)(x-12)=0

x-12=0 i.e x=12 mtr

so the length=12+8=20 mtr

Length :20m Width: 12m
