Answer:
a c d
Step-by-step explanation:
Step-by-step explanation:
6x-2y=5 ........... Equation 1
y=3x+7 ............. Equation 2
Substitute y that's Equation 2 into equation 1 and solve for x
That's
6x - 2( 3x + 7) = 5
6x - 6x - 14 = 5
6x - 6x = 14 + 5
6x - 6x = 19
0x = 19
Divide by 0
x is undefined
Since x is undefined y is also undefined which means that the system has no solutions

Answer:
c³ + cd³ + 3c²d + 3cd²
Step-by-step explanation:
(c+d)^3 is worded as <em>c plus d quantity cubed</em> which doesn't mean you cube everything inside. It means you multiply the quantity by itself 3 times.
(c+d)(c+d)(c+d)
<em>You can only multiply 2 at a time so do the first two then the result and the third one.</em>
<em>Distribute everything in one quantity to the other so </em><em>c*c = c^2 and c*d = cd</em>
= (c^2 + 2cd + d^2)(c+d)
= c^3 + c^2d + 2c^2d + 2cd^2 + cd^2 + cd^3
<em>Combine like terms</em>
= c³ + 3c²d + 3cd² + cd³
10 and I know this because I just looked it up hopefully you have a great rest of ur day
