Answer:
x = 1
y = -5
Step-by-step explanation:
In this question, we need to find what the values of "x" and "y" are.
To do this, we must solve the equations.
Solve:
6x + 2y = -4
3x + 4y = -17
Lets solve for "y" first:
6x + 2y = -4
-2(3x + 4y = -17) = -6x - 8y = 34
Now subtract the two equations from each other.
6x + 2y = -4
-6x - 8y = 34
-6y = 30
Divide both sides by -6
y = -5
Now, we know that the "y" variable's value is -5.
Lets find the value of "x" by plugging -5 to "y" in one of the equations:
6x + 2(-5) = -4
6x - 10 = -4
Add 10 to both sides.
6x = 6
Divide both sides by 6.
x = 1
The value of "x" is 1.
Answer:
x = 22
Step-by-step explanation:
Sides AC and AB are equal, because this is an isosceles triangle.
Therefore, 2x - 24 = x - 2.
Subtracting x from both sides yields x - 24 = -2, and then adding 24 to both sides yields x = 22.

The scale factor for area is the square of the scale factor for linear dimensions. If linear dimensions are scaled up by a factor of 10, the area is scaled up by a factor of 10² = 100.
The area of the larger box is 100×432 cm² = 43,200 cm².
