Switch the second equation to equal y so...
y=-2x-3
then plug in for y in the first equation
2x+4(-2x-3)=6
2x-8x-12=6
-6x=18
x=-3
now plug in for y
2(-3)+y=-3
-6+y=-3
y=3
answer (-3,3)
-18x-12=4
Iam not sure if that’s what you want but basically I multiplied the numbers inside the bracket by -6
Answer:

Step-by-step explanation:
Using Tangent Secant theorem:
(x)² = (2)(2+6)
x² = 2(8)
x² = 16
Answer:
The answer to your question is 64 mm³
Step-by-step explanation:
To calculate the volume of a cube just multiply the length of a side three times.
Data
cube-shaped crystal
length = 4 mm
Formula
Volume = length³
Substitution
Volume = (4 mm)( 4 mm)(4 mm)
Simplification and result
Volume = 64 mm³
Answer:
(11+x)-3
Step-by-step explanation:
11 more than x is another way of saying 11+x
And "less than 3" means subtracting 3 from the terms
So if you put that together it would be
(11+x) -3
