Answer:

see explanation

Step-by-step explanation:

Given

- ( $\frac{2}{5}$ )²

The negative is outside the bracket and is not squared, that is

= - $\frac{2}{5}$ × $\frac{2}{5}$

= - $\frac{2(2)}{5(5)}$ = - $\frac{4}{25}$

Given

$\frac{5^3}{3}$ = $\frac{5(5)(5)}{3}$ = $\frac{125}{3}$

A rectangle on a coordinate plane has vertices L(0, 6), M(8, 6), N(8, 0), and O(0, 0). What are the dimensions of the rectangle?

madam [21]

Based on the given, there are two ways to know the dimensions of the rectangle. First, by simply drawing the coordinates given in a cartesian coordinate plane, P1(0,6),P2(8,6) by looking at the ordinate the length is 6 units, thru P3 (0,0) and P4 (8,0) and looking at the abscissa, the width is 8 units. The second way is through the distance formula, d=sqrt (X2-X1)2+(Y2-Y1)2. The dimensions are L=8 and W=6

What is 96-8c=20-12

galben [10]

Answer:

c = 11

Step-by-step explanation:

96 - 8c = 20 - 12 , that is

96 - 8c = 8 ( subtract 96 from both sides )

- 8c = - 88 ( divide both sides by - 8 )

c = 11
