the height of the triangle is 4cm and the base width is 18 cm and the base length is 18 cm what is the surface area of a square

Gnesinka [82]

Answer:

The surface area is 664 cm²

Step-by-step explanation:

$A=a^{2} +2a\sqrt{\frac{a^{2}}{4} } +h^{2}$ Use this equation to find the surface area

$A=18^{2} +2(18)\sqrt{\frac{18^{2}}{4} } +4^{2}$ Simplify

$A=324 +36\sqrt{\frac{324}{4} } +16$ Simplify

A = 324 + 36√81 + 16 Simplify

A = 324 + 36(9) + 16 Simplify

A = 324 + 324 + 16 Simplify

A = 664 cm²

A certain tv can be purchased from the manufacturer for $160 a certain retailer has a standard markup of 30% abd a certain super

lyudmila [28]

Part A:

The price of the tv when purchased online is given by

$160\left( \frac{100+30}{100} \right)=160\left(\frac{130}{100}\right) \\ \\ =160(1.3)=\$208$

Part B:

The price of the tv when purchased at the superstore is given by:

 $160\left( \frac{100+40}{100} \right)=160\left(\frac{140}{100}\right) \\ \\ =160(1.4)=\$224$

Part C:

The difference between the prices is given by $224 - $208 = 16

For every 10% increase in the markup, the prices increases by $16.

Expand and simplify 2(5x+4)+3(2x-1)

stepladder [879]

2(5x+4)+3(2x-1)

Use the distributive property for both sets of parenthesis:

2(5x+4) = 2*5x + 2*4 = 10x+8

3(2x-1) = 3*2x - 3*1 = 6x-3

Now you have:

10x+8 + 6x-3

Now combine like terms:

10x + 6x = 16x

8-3 = 5

The final answer is 16x+5
