Express {x+1}{2x-3} as a trinomial.

Marizza181 [45]

Answer:

$2x^2 + 5x + 3$

Step-by-step explanation:

First, expand the original equation:

(x + 1)(2x + 3)

$2x^2 + 3x + 2x + 3$

Now simplify:

$2x^2 + 5x + 3$

And that's your answer!

What is the base five representation of The number 219

ICE Princess25 [194]

assuming $219_{10}$

Then the column values for base five here are

5³ 5² $5^{1}$ $5^{0}$

We can get 1 × 5³ = 125 → 219 - 125 = 94

We can get 3 × 5² = 75 → 94 - 75 = 19

We can get 3 x $5^{1}$ → 19 - 15 = 4

and 4 = 4 × $5^{0}$

Thus $219_{10}$ = $1334_{5}$

As a check

(1 × 125 ) + (3 × 25 ) + (3 × 5 ) + 4 = 219

Find the equation of a line that is perpendicular to line g that contains (P, Q). coordinate plane with line g that passes throu

maw [93]

Answer:

$y - Q = - \frac{1}{4}(x - P)$

Step-by-step explanation:

Line g passes through (-2,6) and (-3,2).

The slope of line g is given by:

$\frac{ y_2-y_1}{x_2-x_1}$

Let's substitute the values to get:

$\frac{2 - 6}{ - 3 - - 2}= \frac{ - 4}{ - 1} = 4$

The equation that is perpendicular to line g will have a slope that is the negative reciprocal of 4.

i.e -1/4

If this line passes through (P,Q), then the equation is:

$y - Q = - \frac{1}{4} (x - P)$
