EQUATIONS ON BOTH SIDES solve for -3 + 4x =37

miss Akunina [59]

The answer to this equation would be 10!

Steps:
Add 3 to both sides of the equation this would add 3 to 37 making it 40 and when you add 3 to -3 it cancel out so the new equation should look like this!

4x=40

The next step is to divide both sides by four and you get the answer!

X=10

find an equation for the line through (4,7) with the given relationship to y=2x-4: a. parallel & b. perpendicular

stiks02 [169]

A.) Parallel lines has equal slopes, hence slope of required equation = slope of y = 2x - 4 = 2
required equation is y - y1 = m(x - x1)
y - 7 = 2(x - 4)
y - 7 = 2x - 8
y = 2x - 8 + 7
y = 2x - 1

A regulat pentagon has side lenghts of 5.8cm and apothem of 4cm. calculate its perimeter and area

Kryger [21]

PENTA = 5.

a regular polygon has all equal sides, so if one side is 5.8, all are, so the perimeter for this pentagon with 5 sides is 5.8 + 5.8 + 5.8 + 5.8 + 5.8 = 29.

$\bf \textit{area of a regular polygon}\\\\ A=\cfrac{1}{2}ap~~ \begin{cases} p=perimeter\\ a=apothem\\ \cline{1-1} p=29\\ a=4 \end{cases}\implies A=\cfrac{1}{2}(4)(29)\implies A=58$
