If the sides of a square are increased by 3 inches, the area becomes 64

Mathematics

seropon [69]3 years ago

Answer:

Length\ of\ the\ side=5\ inches

Step-by-step explanation:

Let x be the length of the sides of the original square.

Given:

The sides of a square are increased by 3 inches, the area becomes 64

So, the length of the side x+3

The area of the square is

Area=(length\ of\ the\ side)^{2}

Area=(x+3)^{2}

Substitute area value in above equation.

64=(x+3)^{2}

(x+3)=(64)^{\frac{1}{2}}

x+3=\sqrt{64}

x+3=\sqrt{8^{2}}

x+3=8

x=8-3

x=5\ inches

Therefore, the length of the sides of the original square is 5 inches.

Side-Side-Side, SSS, congruency postulate states that if three sides of

one triangle are congruent to three sides of another triangle, the two

triangles are congruent.

aivan3 [116]

9514 1404 393

Answer:

  d = 290 -3x

Step-by-step explanation:

For each x feet that Armondo travels toward Bianca, Bianca travels 2x feet toward Armondo. The net effect is that the distance between them decreases by x+2x = 3x feet. The distance starts at 290 feet when x=0, so the distance can be described by ...

  d = 290 -3x

Need help with #11. The answer is about 13.86 years but show work please.
tangare [24]

Answer:

13.86

Step-by-step explanation:

formula for cont. compounding interest is

Amount = Principal * e^rt

in this case the principal is 5000, and the amount is 10000 (double). the rate is 5% or 0.05. and t is what we are solving for.

sub in to get:

10000 = 5000e^0.05t

2 = e^0.05t

now convert to log form.

ln 2 = 0.05t

ln 2 / 0.05 = t

punch that into your calculator and you get 13.86 years
