In the top right corner is -7x since we multiply the x and -7

In the bottom row, we'll have 5x for the first box and -35 for the second box. Each box is the result of multiplying the outer values.

In the top left corner, the x^2 is from multiplying the two copies of x.

Tommy Blox borrowed $4000 from a bank at 12% simple interest.After 3 years,he paid back the loan plus the interest.How much did
Juli2301 [7.4K]

The formula we'll use for this is the simple interest formula, or:

Where:

<span><span>P is the principal amount, $4000.00.
</span><span>r is the interest rate, 12% per year, or in decimal form, 12/100=0.12.
</span><span>t is the time involved, 3....year(s) time periods.
</span><span>So, t is 3....year time periods.
</span></span>

To find the simple interest, we multiply 4000 × 0.12 × 3 to get that:

<span>The interest is: $1440.00</span>

Which geometric figure has the greatest perimeter?
Fofino [41]

Answer:

Triangle has the greatest perimeter

Step-by-step explanation:

Triangle:

2\sqrt{48}=2\sqrt{2*2*2*2*3}=2*2*2\sqrt{3}=8\sqrt{3}\\\\\\3\sqrt{75}=3*\sqrt{3*5*5}=3*5*\sqrt{3}=15\sqrt{3}\\\\\\6\sqrt{12}=6*\sqrt{2*2*3}=6*2*\sqrt{3}=12\sqrt{3}\\\\\\2\sqrt{108}=2*\sqrt{2*2*3*3*3}=2*2*3*\sqrt{3}=12\sqrt{3}\\\\\\3\sqrt{147}=3*\sqrt{3*7*7}=3*7\sqrt{3}=21\sqrt{3}\\\\Perimeter=3\sqrt{147}+2\sqrt{108}+6\sqrt{12}+2\sqrt{48}+3\sqrt{75}\\\\  =21\sqrt{3}+12\sqrt{3}+12\sqrt{3}+8\sqrt{3}+15\sqrt{3}\\\\=(21+12+12+8+15)\sqrt{3}\\\\=68\sqrt{3}\\

= 68 * 1.732 = 117.78

Square:

\frac{1}{3}\sqrt{63}=\frac{1}{3}\sqrt{3*3*7}=\frac{1}{3}*3*\sqrt{7}=\sqrt{7}\\\\Perimeter=4*side=4*\sqrt{7}=4\sqrt{7} = 4* 2.6458 = 10.58

Rectangle:

\frac{1}{4}\sqrt{100}=\frac{1}{4}\sqrt{10*10}=\frac{1}{4}*10=\frac{5}{2}\\\\\\Perimeter=\frac{1}{4}\sqrt{100}+2\sqrt{48}+4\sqrt{75}+\frac{1}{4}\sqrt{100}+2\sqrt{48}+4\sqrt{75}\\\\=\frac{5}{2}+8\sqrt{3}+20\sqrt{3}+\frac{5}{2}+8\sqrt{3}+20\sqrt{3}\\\\=\frac{5+5}{2}+(8+8+20+20)\sqrt{3}  \\\\=\frac{10}{2}+56\sqrt{3}+\\\\=5+56\sqrt{3}\\\\=5+56*1.732=5+96.99=102

A department store sells a pair of shoes with an 87% markup. If the store-bought the pair of shoes for $55.25, what is the selli
olga_2 [115]
Answer: $103
Explanation:
Stores will markup an item to make a profit so this question is asking how much they will be selling the shoes to the customer.
To solve this problem we will start by multiplying the price the store payed for (55.25) by the percentage in decimal form (.87)
55.25•0.87=48.0675

We then add the markup to the price payed for the shoes.
55.25+48.0675=103.3175

When rounding to the nearest dollar we look at the digit in the tens place (3) and since 3 is < 5 we round the final price to $103
