Think of square roots of the same numbers as being like terms.
Think of
5x + 12y - 10x - 5y =
= 5x - 10x + 12y - 5y
= -5x + 7y
Think of sqrt(7) as x, and sqrt(6) as y.
Answer:
B) y = -3x+2
Step-by-step explanation:
plug (2,-4) and -3 into y = mx + b to find 'b'
-4 = -3(2) + b
b = -4+6 = 2
UT = 3 √3
A = 1/2 *12 * 3√3 = 18√3
18√3 = 6y/2
y = 6√3
Answer:
A = 42 cm^2
Step-by-step explanation:
To find the area of a rectangle , multiply the length and the width
A = lw
A = 7cm * 6 cm
A = 42 cm^2
