What is the solution to this equation 4x + 2 ( x + 6 ) = 36

Margaret [11]

The answer is A. x=4.

Start off by distributing the parentheses into the equation.

4x+2(x+6)=36

4x+2x+12=26

Combine like terms.

4x+2x=6x

6x+12=36

Now solve the equation as normal. Begin by subtracting 12 from both sides to isolate the variable.

6x+12=36

-12 -12

---------------

6x = 24

Divide 6 on both sides to find x.

6x=24

---- -----

6 6

x=4

The solution to the equation is 4.

What is the value of A when we rewrite... (PLZ HELP QUICK)

Marina86 [1]

Answer:

Step-by-step explanation:

Given,

${( \frac{5}{2} )}^{x} + {( \frac{5}{2} )}^{x + 3}$

$= {( \frac{5}{2}) }^{x} + {( \frac{5}{2}) }^{x} \times {( \frac{5}{2} )}^{3}$

$= ( \frac{5}{2} ) ^{x} (1 + {( \frac{5}{2} )}^{3}$

$= {( \frac{5}{2} )}^{x} (1 + \frac{125}{8} )$

$= {( \frac{5}{2} )}^{x} ( \frac{1 \times 8 + 125}{8} )$

$= {( \frac{5}{2}) }^{x} ( \frac{8 + 125}{8} )$

${( \frac{5}{2} )}^{x} ( \frac{133}{8} )$

Comparing with A • ${( \frac{5}{2}) }^{x}$

A = $\frac{133}{8}$

Hope this helps...

Good luck on your assignment...

Answer:

A linear formula for S as a function of D is S=17D+1534

Step-by-step explanation:

We are supposed to find a linear formula for S as a function of D.

Equation of line : y = mx+c

We are given that At the surface, the speed of sound is 1534 meters per second.

c = 1534

We are given that for each increase in depth by 1 km, the speed increases by 17 m/s

So, Slope = m = 17

Substitute the values in equation

y=17x+1534

x denotes depth

y denotes speed

We are given that Use D for depth and S for the speed of sound

So, S=17D+1534

Hence a linear formula for S as a function of D is S=17D+1534

The solution to a quadric equation are x=2 and x=7. If k is a nonzero constant which of the following must be equal to the quadr

nikklg [1K]

Answer:

The quadratic equation form is x² - 9 x + 14 = 0

Step-by-step explanation:

Given in the question as ,

The solution of quadratic equation are x = 2 and x = 7

The constant K is a non-zero number

Now , let the quadratic equation be , ax² + bx + c = 0

And sum of roots = $\frac{ - b}{a}$

product of roots = $\frac{c}{a}$

So, 2 + 7 = $\frac{ - b}{a}$

Or, 2 × 7 = $\frac{c}{a}$

I.e $\frac{ - b}{a}$ = 9 , $\frac{c}{a}$ = 14

Or, b = - 9 a And c = 14 a

Put this value of b and c in standard form of quadratic equation

I.e ax² + bx + c = 0

Or, ax² - 9 ax + 14 a = 0

Or , a ( x² - 9 x + 14 ) = 0

∴ a = 0 And x² - 9 x + 14 = 0

Hence , The quadratic equation form is x² - 9 x + 14 = 0 Answer
