The value of x is 3
<h3>How to solve for x?</h3>
The given parameters are:
Length = 10cm
width = 2cm
Height = x
The surface area is calculated as;
Area = 2 *(lw + lh + wh)
So, we have:
2 * (10 * 2 + 2x + 10x) = 112
Evaluate the like terms and divide by 2
20 + 12x = 56
Subtract 20 from both sides
12x = 36
Divide by 12
x = 3
hence, the value of x is 3

Answer: omg i need help with the exact same question
Step-by-step explanation:
Answer:
Question 2 the answer is C) y = -3/2x + 2
Question 3 the answer is D) x = 4
Step-by-step explanation:
To solve either we first need to know that parallel lines have the same slope.
So in #2 we know that the new line will also have a slope of -3/2. Therefore, we can use that along with the point given in the problem in point-slope form to get the new equation.
y - y1 = m(x - x1)
y + 1 = -3/2(x - 2)
y + 1 = -3/2x + 3
y = -3/2x + 2
And for #3, we know that we have a vertical line due to the fact that it is expressed as x = a number. Therefore, we must have the same in the answer. D is the only one that has such an answer.
Ax^2 = bx Divide by x
ax^2/x = b
ax^(2 -1) = b
ax = b Divide by a
x = b/a
