Simplify using PEMDAS(3X + 2x)(3+4)

Answer:

$5x*7$

Step-by-step explanation:

We know that PEMDAS is a shortened acronym for the order in which we do operations in an expression, which is as following in the correct order:

Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction.

Now your question asks you to solve the expression using PEMDAS, however that is what we would do regardless as in algebra PEMDAS is always in effect.

Lets break it down! $(3x+2x)*(3+4)$

Simple enough! We just do the respective operations inside the parenthesis first (as per pemdas), which after completion yields us

$5x*7$

Since x is undefined and the expression is completely simplified, there is nothing more we can do.

HELP IVE BEEN STRUGGLING FOR THE PAST 15 MIN PLEASEEEEE

Answer:

c= -1/2

Step-by-step explanation:

Let's solve your equation step-by-step.

4 /3 = −6c − 5/ 3

Step 1: Simplify both sides of the equation.

4 /3 =−6c + −5 /3

Step 2: Flip the equation.

−6c + −5 /3 = 4/3

Step 3: Add 5/3 to both sides.

−6c + −5 /3 + 5 /3 = 4/3 + 5 /3 −6c

Step 4: Divide both sides by -6.

−6c −6 = 3 − 6 c = −1 /2

A stone is thrown vertically upward from a platform that is 20 feet height at a rate of 160 ft/sec. Use the quadratic function h

Nutka1998 [239]

Check the picture below.

$\textit{vertex of a vertical parabola, using coefficients} \\\\ y=\stackrel{\stackrel{a}{\downarrow }}{-16}x^2\stackrel{\stackrel{b}{\downarrow }}{+160}x\stackrel{\stackrel{c}{\downarrow }}{+20} \qquad \qquad \left(-\cfrac{ b}{2 a}~~~~ ,~~~~ c-\cfrac{ b^2}{4 a}\right)$

$\left(-\cfrac{ 160}{2(-16)}~~~~ ,~~~~ 20-\cfrac{ (160)^2}{4(-16)}\right) \implies \left( - \cfrac{ 160 }{ -32 }~~,~~20 - \cfrac{ 25600 }{ -64 } \right) \\\\\\ \left( 5 ~~~~ ,~~~~ 20 +400 \right)\implies (\stackrel{seconds}{5}~~,~~\stackrel{feet}{420})$
