base: b

height: b

A = 1/2 (b · b) = 1/2(b²) = b²/2

sum is six less than area

b + b = 6 - ↔b²/2

2b = b²/2 - 6

4b = b² - 12 <em>multiplied by 2 to clear the denominator</em>

0 = b² - 4b - 12

0 = (b - 6)(b + 2)

0 = b - 6 0 = b + 2

b = 6 b = -2 (Negative so disregard)

A = b²/2 = (6)²/2 = 36/2 = 18

Answer: 18 units²

alex41 [277]

Answer:

2x - 1

Step-by-step explanation:

Since logarithm has the following property:

If $f(x)=b^x$ and $g(x)=\log_bx$ ,

Then $fog=b^{\log_bx}=x$ and $gof=\log_bbx=x$

Therefore,

$- 1 + \ln e^{2x} = - 1 + \log_e e^{2x} = 2x-1$

Sumeet is building two types of birdhouses. The more traditional type takes 4 pieces of wood and 2 hours to build. The more lavi

mina [271]

Answer:

The no. of traditional type birdhouses are 4 and the no. of lavish type birdhouses are 3.

Step-by-step explanation:

Let x be the no. of traditional type birdhouses

The more traditional type takes 4 pieces of wood and 2 hours to build.

One house requires wood = 4

x houses requires wood = 4x

One house requires time = 2 hours

x houses requires time = 2x

Let y be the no. of lavish type birdhouses

The more lavish type takes 10 pieces of wood and 7 hours to build.

One house requires wood = 10

y houses requires wood = 10y

One house requires time = 7 hours

y houses requires time = 7y

Now we are given that he has a total of 46 pieces of wood and 29 hours to work,

So, equations becomes : $4x+10y = 46\\2x+7y=29$

Plot these equations on graph

$4x+10y = 46$ ---Blue line

$2x+7y=29$ ---Green line

Refer the attached figure

The intersection point provides the solution

Intersection point : (4,3)

So, x = 4 and y = 3

Hence the no. of traditional type birdhouses are 4 and the no. of lavish type birdhouses are 3.
