Answer:

x = 20

Step-by-step explanation:

Since the polygons are similar then the ratios of corresponding sides are equal, that is

$\frac{5}{10}$ = $\frac{10}{x}$ ( cross- multiply )

5x = 100 ( divide both sides by 5 )

x = 20

Answer:

Answer is 20.

Step-by-step explanation:

Since they are similar thus ratio of sides would be equal the top side is double of the first polygon. so the side x wud be double of 10. which is 20

Dominic is building a bench with a seat in the shape of a trapezoid. One base is 5 feet. The other base is 4 feet. The perpendic

Vlad [161]

By definition, the formula for finding the area of a trapezoid is
A = [(b1 + b2) x h] / 2
Where,
b1: Base 1
b2: Base 2
h: height, or distance between bases.
Substituting we have:
A = ((5 + 4) * (2.5)) / 2
A = 11.25 feet ^ 2

Answer:
the area of the seat is:
A = 11.25 feet ^ 2

Solve logarithm Equation: log2 (12b - 21) - log2 (b^2 - 3)=2

Vikki [24]

Hn, well you should use the rule to answer this.. $log_a(n)-log_a(m)=log_a (\frac{n}{m} )$
Sorry if this doesn't seem to help, but here is the explanation:
$log_2 (\frac{12b-21}{b^2-3} )=2$
$\frac{12b-21}{b^2-3} =4$
$12b-21=4(b^4-3)$
$0=4b^2-12b-12+21$
$0=4b^2-12b+9
$
$0=4b^2-6b-6b+9$
$0=2b(2b-3)-3(2b-3)$
$0=(2b-3)(2b-3)$
$b= \frac{3}{2}$
Hn, so from this information we can determine that this solution does not work. And so forth your solution set shall indeed be: {x= 0}

I wish you good luck on your homework and hopefully I was somewhat beneficial to your needs.

Help me please help.

Answer:

steps below

Step-by-step explanation:

This is a contradictory proof of sophistry

f(x+4) = f(x)+f(4) ...(1) when x=0

f(x+4) = f(0+4) = f(4) = f(x) + f(4)

f(x) = f(4)-f(4) = 0

From (1): f(x) = f(x+4) - f(4)

x=-4 f(-4) = f(-4+4) - f(4) = f(0) - f(4) = -f(4) ...(2)

From (1): f(x+4) = f(x)+f(4)

x=4 f(4+4) = f(8) = f(4) + f(4) = 2f(4) = -2f(-4) from (2) ... (3)

f(8) +2f(-4) = -2f(-4) + 2f(-4) = 0
