A cross-shaped pattern is made by arranging four identical rectangles around the side of a square, as shown in the diagram.
const2013 [10]

Answer:

88 cm

Step-by-step explanation:

The side of the square = 6 cm, so the shorter side of each rectangle = 6 cms.

The area of each rectangle =  36 *  1 1/3

= 36 * 4/3 = 48 cm^2

So the longer side of each rectangle = 48 / 6 =  8 cms

Therefore, the perimeter of the whole figure

=  4( shorter sides ) + 8(longer sides)

= 4*6 + 8*8

= 24 + 64

= 88 cm   (answer)

Sal Boxer decided to divide a gift of $5000 into two different accounts. He placed $1000 in an account that earns an annual simp
mash [69]

Answer:

THE TOTAL INTEREST EARNED = $ 385

Step-by-step explanation:

Interest earned by sal from first account can be calculated as follows :

Principal value (P)  =  $1000 .

interest rate (R)  =  7.5 % .

Time period (T) =  1  year .

\textbf{S . I} =\frac{\texbf{P * R * T}}{\textbf{100}}

        = \frac{1000 * 7.5 * 1}{100}

         = $ 75 .

SIMILARLY , we can find the intrest earned by rest amount.

Principal value (P) = $5000 - $ 1000 = $ 4000 .

Interest rate (R) = 7.75 % .

Time period (T) = 1 year .

S . I =  \frac{4000 * 7.75 * 1}{100}

      = $ 310 .

THE TOTAL INTEREST EARNED = $ 75 + $ 310

                                                       = $ 385

How do you simplify (-1 - 3 √(3) × (-1 - 3 √(3)
harina [27]

Answer:

4 + 6√(3)

Step-by-step explanation:

Two right parentheses seem to be missing here.  I think you meant:

(-1 - 3 √(3) ) × (-1 - 3 √(3) )

and this is the square of a binomial.  The resulting square is:

1 + 6√3 + 3, or 4 + 6√(3)
