Let k ( x ) = 2 x + 3 and m ( x ) = 3 x 2 + 7 x − 10 . Find the indicated value. M ( k ( − 4 ) ) =

murzikaleks [220]

Answer: $30$

Step-by-step explanation:

Given

$k(x)=2x+3$

$M(x)=3x^2+7x-10$

$M\left(k(x)\right)$ is given by replacing the $x$ by $k(x)$ from the $M(x)$

$\Rightarrow M\left(k(x)\right)=3(2x+3)^2+7(2x+3)-10\\\Rightarrow M\left(k(x)\right)=3(4x^2+9+12x)+14x+21-10\\\Rightarrow M\left(k(x)\right)=12x^2+50x+38$

Now, $M\left(k(-4)\right)$ is

$\Rightarrow M\left(k(-4)\right)=12(-4)^2+50(-4)+38\\\Rightarrow M\left(k(-4)\right)=192-200+38\\\Rightarrow M\left(k(-4)\right)=30$

The length of a rectangle is 12 inches. The width of the rectangle is 5 inches. Mia says the perimeter is 60 in2 and the area is

larisa86 [58]

Answer:

Mia is incorrect.

Step-by-step explanation:

She confused the area and perimeter.

Area is length x width, in this case 12 x 5 = 60

Perimeter is length² × width², and in this case, it is 12² × 5² = 34

Area = 60 inches

Perimeter = 34 inches

Hope that helps and have a great day!
