Answer:
the answer would be 21x^3 - 12x^2y^4, because you want to multiply 3x^2 and 7x first to make 21x^3, and then multiply 3x^2 and -4y^4 to get -12x^2y^4. hope that helps!
Answer:
(-3,2)
Step-by-step explanation:
look at the dot called K, straight down you see -3 which is your X and if you look straight to the right of point K you see 2 which is your Y
(the whole bolded line that is horizontal is ur X and the whole bolded vertical line is ur Y)
If i am understanding the question correctly, x<10
The product of side length and altitude is area. The area remains the same regardless of how you measure it.
From the first side and altitude,
.. area = side*altitude = (4.2 cm)*(3.6 cm) = 15.12 cm^2
From the second side and altitude
.. area = side*altitude
.. 15.12 cm^2 = side*(2.4 cm)
.. side = (15.12 cm^2)/(2.4 cm) = 6.3 cm
The perimeter is the sum of the measures of all sides. Opposite sides are of equal measure.
.. perimeter = 2*(4.2 cm +6.3 cm) = 21.0 cm
