Evaluate 3(a + b + c)2 for a = 2, b = 3, and c = 4

Verdich [7]

Answer: 243

Step-by-step explanation:

We have the expression

$3(a + b + c)^2$

Note that the expression depends on 3 variables

a, b and c

in this case we want to evaluate the expression for

$a = 2\\b = 3\\c = 4$

Then change the variable a by the number 2, the variable b by the number 3 and the variable c by the number 4

So we have

$3(2 + 3 + 4)^2$

Now simplify the expression

$3(9)^2$

$3*81=243$

The answer is 243

The area of of a triangle is 56 m² give all possible sets of whole number dimensions for the base and height ot the triangle

ch4aika [34]

$\bf \textit{area of a triangle}\\\\ A=\cfrac{1}{2}bh~~ \begin{cases} b=base\\ h=height\\ \cline{1-1} A=56 \end{cases}\implies 56=\cfrac{1}{2}bh\implies 112=bh \\\\\\ \boxed{112=2\cdot 2\cdot 2\cdot 2\cdot 7}\to \begin{cases} 16\cdot 7\\ 8\cdot 14\\ 4\cdot 28\\ 2\cdot 56 \end{cases}\qquad or\qquad \begin{cases} 7 \cdot 16\\ 14 \cdot 8\\ 28 \cdot 4\\ 56 \cdot 2 \end{cases}$

so their product is 112, so tis just a matter of doing some quick prime factoring and combining the factors about.

What is the slope of the line shown below? (3,6) (1,-2)

mrs_skeptik [129]

Points (3,6) and (1,-2)

Slope (m) = $\frac{Change in y}{Change in x}$

Change in y = -2 - 6 = -8

Change in x = 1 - 3 = -2

Slope (m) = -8 ÷ -2 = 4

Stefanie spends entire allowance one month she spends 1/2 of a on new clothes 1/4 on food 1/6 on movies and 1/12 on Music how mu

Komok [63]

Answer:

Option D: 1/3

Step-by-step explanation:

Let

x ------> the entire Stefanie's allowance

we know that

She spends on clothes (1/2)x

She spends on movies (1/6)x

To find out how much more does she spend on clothes that he does on movies, subtract the amount she spends on movies from the amount she spend on clothes

$\frac{1}{2}x-\frac{1}{6}x=\frac{2}{6}x$

Simplify

$\frac{1}{3}x$

therefore

She spends 1/3 more on clothes that he does on movies
