It will be 4:9 as well.
Circumference = 2πr,
r1 : r2 = 4:9 so this means that 2πr1 : 2πr2 = 4:9, because 2π = constant

2. If f(x) = x - 7 and g(x) = 2x + 5, then what is f(x) * g(x)?
AysviL [449]

Answer:

2x² - 9x - 35

Step-by-step explanation:

f(x) × g(x) = (x - 7)(2x + 5)

Each term in the second factor is multiplied by each term in the first factor, that is

x(2x + 5) - 7(2x + 5) ← distribute both parenthesis

= 2x² + 5x - 14x - 35 ← collect like terms

= 2x² - 9x - 35

Evaluate the expression when x=10, y=−2, and z=−5.
Vlad [161]

\frac{ -  {x}^{2} + 6z }{y}

if x=10 y=-2 and z=-5 then...

\frac{ { - 10}^{2}  + 6 \times  - 5}{ - 2}

we solve this to get...

<em>65</em>

therefore the answer to your question would be 65

The sides of a triangle are in the ratio of 2:3:4. If the measure of the shortest side of the triangle is 12 centimeters, what i
Scorpion4ik [409]
To answer this, we let x some factor that would agree or make the ratio given true. We calculate as follows:

<span>2:3:4
2x:3x:4x

2x = 12
x = 6 

Therefore, the length of the longest side would be 4x = 4(6) = 24 cm, third option.</span>
