Answer:

(x + 7)(2x + 3)

Step-by-step explanation:

Given

2x² + 17x + 21

Consider the factors of the product of the x² term and the constant which sum to give the coefficient of the x- term.

product = 2 × 21 = 42 and sum = + 17

The factors are + 14 and + 3

Use these factors to split the x- term

2x² + 14x + 3x + 21 ( factor the first/second and third/fourth terms )

= 2x(x + 7) + 3(x + 7) ← factor out (x + 7) from each term

= (x + 7)(2x + 3) ← in factored form

The radius r of a circle is increasing at a rate of 7 centimeters per minute. (a) find the rate of change of the area when r = 1
VikaD [51]
Dr /dt = 7

A = pi r^2

dA / dr = 2pir

dA/dt = dA/dr  * dr/dt = 2pir * 7  = 14pir

when r = 12   rate of change of the area =  14*pi*12  =  168pi

            =  527.79 cm^2 / minute to nearest hundredth

What is<br> 3Vsquare27 + v64square -2
serg [7]

Answer:

Step-by-step explanation:

I think you are inventing symbols, which turns your question into a guessing game. You are better off describing the math symbols in words. Or post a picture.

I’m guessing that the math expression is ∛27 + √64² - 2 = 3 + 64 - 2 = 65

What is 5( x - 3 ) = 5x - 15?
Volgvan

\tt5( x - 3 ) = 5x - 15 \\  \tt5x - 15 = 5x - 15 \\ \tt5x - 5x =  - 15 + 15 \\ \tt\bcancel{5x} - \bcancel{5x} =  \bcancel{- 15} + \bcancel{15} \\ \boxed{\tt0 = 0}

  • The answer is <u>0</u><u>.</u>
  • LHS = RHS, hence verified.

<u>Value of x (substitute 0 in the place of x).</u>

\tt5( (0) - 3 ) = 5(0) - 15 \\  \tt0 - 15 = 0 - 15 \\  \tt \boxed{\tt -15 = -15}

  • So, value of x is <u>0</u><u>.</u>
