Question 1 answer: The first and last option.
Question 1 explanation: 2(4x + 2) is 4x = 12 = 2 = 14 x 2 = 28 and 8x + 4 is 8 x 4 = 32 + 4 = 36 which is 8 more than 28 then, 3x = 9 + 2 + 3 x 2 = 28.
2(4x + 2) = 28 and 8x + 4 equals 36 which is 8 more and they're both equivalent to 2(3x + 2 + x) because 2(3x = 2 = x) equals 28.

yes, there are an infinite number of solutions
Step-by-step explanation:
The attached graph shows values of A and B (x and y) that can make this equation be true. Any of the points on any of the curves will satisfy the equation. (The repetition continues indefinitely in all directions.)
Answer:
Equation 2 is non-linear, Equation 1 is linear.
Step-by-step explanation:
A linear equation is an equation with a constant gradient and can be expressed in the form y = mx + c. Hence Equation 1 Satisfies this as it is in that form and has a constant gradient of 4. Equation 2 is not in the form y = mx + c since there is a square and hence its non-linear.
Answer:
a. 18 cm
Step-by-step explanation:
We are given that a circle has an area of 324π cm2. We are required to determine its radius. The formula for the area of a circle with radius r units is;
We plug in the area given and solve for r;
The radius of the circle is 18 cm
