1. Solve by using the Elimination method for solving systems of equations.
2. Top equation, minus, the other equation on the bottom. (4x-9y=-21)-(4x+3y=-9)
3. Subtract like terms.
4x-4x = 0
-9y - 3y = -12y
-21 - -9 = -30
4. Isolate for y
y= -30/-12 =5/2
5. Plug the value of y into original equation and isolate for x.

What is the cube root of 27 in radical notation ​
vitfil [10]

Answer: hi im mongraal

Step-by-step explanation:

In mathematics, a cube root of a number x is a number y such that y³ = x. All nonzero real numbers, have exactly one real cube root and a pair of complex conjugate cube roots, and all nonzero complex numbers have three distinct complex cube roots. For example, the real cube root of 8, denoted ³√8, is 2, because 2³ = 8, while the other cube roots of 8 are −1 + √3i and −1 − √3i. The three cube roots of −27i are 3i, 3√(3)/2-3/2i, and -3√(3)/2-3/2i.

I am Lyosha [343]
2x + 2y = 20
2(6) + 2y = 20
12 + 2y = 20
2y = 8
y = 4
width = 4

Area = 6 × 4
= 24 cm
