Step 3

EXPLANATION

The given polynomial expression is:

$2 {p}^{2} - 3p - 7 - (3 {p}^{2} + p - 5)$

Fatau correctly expanded the parenthesis in the first step.

$2 {p}^{2} - 3p - 7 - 3 {p}^{2} - p + 5$

Fatau also correctly grouped the like terms to obtain:

$(2- 3) {p}^{2} + (- 3 - 1)p + (- 7 + 5)$

Fatau committed a mistake at the third step.

Instead of obtaining,

$- {p}^{2} - 4p - 2$

He mistakenly got:

${p}^{2} - 2p +2$

Answer:

$f(g(x)) = 6x^2+6x+11$

Step-by-step explanation:

$f(g(x)) = 2(3x^2+3x+7) - 3\\f(g(x)) = 6x^2 + 6x + 14 - 3\\f(g(x)) = 6x^2+6x+11$

Answer:

If the units in the equation are in feet, it lef5t at a height of 7.4 feet (or meters, etc.).

Step-by-step explanation:

p(x) = - 0.013x2 + 0.02x + 7.4

When x, the time, = 0 [just before it leaves the pitcher's hand]

p(0) = 7.4

The perimeter of a rectangle is given by the formula P = 2(l + w), what is the value of P if l = 2 cm and w = 1/2 cm?

Sonja [21]

Answer:

$\large\boxed{C)\ 5cm}$

Step-by-step explanation:

$P=2(l+w)\\\\\text{Put}\ l=2cm\ \text{and}\ w=\dfrac{1}{2}cm\ \text{to the formula of the perimeter:}\\\\P=2\left(2+\dfrac{1}{2}\right)=(2)(2)+(2)\left(\dfrac{1}{2}\right)=4+1=5\ cm$
