Twelve and six hundred seven thousandths
so we have a 60-30-90 triangle (top one)
so since we know 6 is x (the side on the right angle and 60 degrees)
b is 2x or 2(6) = 12
a is x√3 = 6√3
for C I need to use a 45 45 90 triangle
Since b is 12 and its x√2 to find x we should write it as
x√2 = 12
√2 √2 divide by √2
x = 12/√2 but we must rationalize the denominator
12/√2 times √2/√2 = 12√2/2 and that's c
The required equation in slope-intercept or standard form is y = 2x+12.
It is required to find the equation in slope-intercept or standard form.
<h3>What is slope?</h3>
Numerical measure of a line's inclination relative to the horizontal. In analytic geometry, the slope of any line, ray, or line segment is the ratio of the vertical to the horizontal distance between any two points on it.
Given:
The equation of the line that is parallel to y=2x-4.
Parallel lines have the same slope, We know the equation will be
y = 2x + b.
Use the point (-7,-2) to sub in for (x, y) to solve for b.
-2 = 2(-7) + b
-2=-14+b
12=b
So, the equation will be y = 2x+12
Therefore, the required equation in slope-intercept or standard form is y = 2x+12.

Answer: 13 sheets of paper
Step-by-step explanation:
We are given the dimensions of the box and the wrap paper:
Box:
Warp paper:
Now we need to find the surface area of the box and the area of the wrap paper:
Box:
Warp paper:
Dividing the area of the box by the area of the paper:
This means Angel's dad needs to purchase 13 sheets of wrapping paper.
