Scale Drawings question

Mathematics
1 answer:
Nimfa-mama [501]3 years ago
6 0

Answer:

138 is the answer

Step-by-step explanation:

In order to find the perimeter, we use this formula

P=2(l+w)

And to find the width, we use this formula

w = P/2 - L = 18/2 - 3 = 6

So the width is 6

3 × 6 = 18

So thats why the perimeter of the top triangle is 18

We do 21 ÷ 3 = 7, 7 = scale factor

To find the perimeter of the bottom triangle, we do

the width of the top rectangle times 7

so 6 × 7 = 48

So the perimeter for the bottom triangle is

P=2(l+w)=2·(48+21)=138

Write the equation Of a function who parent function, f(x)=x+8 is shifted 2 units to the right
Juli2301 [7.4K]

Answer:

g(x)=x+6

Step-by-step explanation:

we have

f(x)=x+8

If f(x) is shifted 2 units to the right

then  

The rule of the translation is

g(x)=f(x-2)

so

g(x)=(x-2)+8

g(x)=x+6

Whats wrong in this equation ?
Inga [223]
The second step is wrong. What should've been done is to find greatest common factor (gcf) of 1/6 and -2. This is because you cannont add together a number with a variable to a number without a variable. So get the variable by itself by subtracting 1/6 from both sides.

1/5x + 1/6 = -2
___— 1/6_— 1/6
____________


Turn -2 into a fraction and find the gcf of -2 and 6:

1/5x + 1/6 = -2
___— 1/6_— 1/6
____________

1/5x = -2/1 — 1/6 ——> 1/5x = -12/6 — 1/6
1/5x = -13/6

Then divide each side by 1/5 to get the variable by itself; remeber: when dividing a fraction by a fraction, you multiply by the reciprocal.

5/1 • 1/5x = -13/6 • 5/1
x = 65/6

Then, simplify

65/6} 10.83 or 10 83/100

Which expression is equivalent to 4(6 + 8)?
hoa [83]

Answer:

You would have to add the expression so we know what you're talking about.

Any multiple of those numbers is equivalent though.

Hello can someone please help me ?

Vertical asymptotes can be found by setting the denominator equal to 0

x^2-6x = 0
factor out x
x(x-6)
set the two parts equal to 0
x = 0

x-6 = 0
x = 6

so the two x values are 0 and 6

ANSWER: B. x = 0, x = 6
