Answer:

5√3-7√2+2

Step-by-step explanation:

3√2√6−√3+2√3√6+ 2-4√3√6−√2

Bringing the like terms

3√2√6-2√3√6−√2−√3+2

Now we apply the rule which says

√a x√b = √ab

3√(2x6)-2√(3×6)-√2-√3+2

3√(2x2×3)-2√(3×3×2)-√2-√3+2

3×2√3-2×3√2-√2-√3+2

6√3-6√2-√2-√3+2

Bringing the like terms together

6√3-√3-6√2-√2+2

5√3-7√2+2

What does x equal to x/7 - 4 = -5
beks73 [17]

Answer:

x = -7

Step-by-step explanation:

So we are asked to find what x is equal to in the equation:

\frac{x}{7}-4=-5

In other words, we are asked to solve for x.

\frac{x}{7}-4=-5

Add 4 to both sides of the equation.

\frac{x}{7}=-1

Multiply both sides by 7.

x = -7

So we have solve the equation for x and have found that x = -7.

Write the equation of a line parallel to the line y = 5x + 2 that passes through the point (2,1).
pentagon [3]

Answer:

\large\boxed{y=5x-9}

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

Parallel lines have the same slope. Therefore if given line is

y=5x+2

then the slope of our line is m=5.

We have the equation:

y=5x+b

The line passes through (2, 1). Put the coordinsted pf the point to the equation:

1=5(2)+b

1=10+b           <em>subtract 10 from both sides</em>

-9=b\to b=-9

Finally:

y=5x-9
