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.
Use 3.14 for π .
Enter your answer as a decimal in the box.
Answer: 530.66 is the answer
Hope u get a good grade
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
Answer:
4.5 square centimeters
Step-by-step explanation:
base, b of triangle ABD = 3 cm
Height, h of triangle ABD = 3 cm
Area = 1/2 b*h
Area of triangle ABD = 1/2 * 3 *3
= 1/2 * 9
= 4.5 square centimeters
