Correct version

$\\ \rm\Rrightarrow (x^3+2x^2-x)-(3x^3-3x^2+2x-4)$

$\\ \rm\Rrightarrow x^3+2x^2-x-3x^3+3x^2-2x+4$

$\\ \rm\Rrightarrow x^3+5x^2-3x+4$

Not multiplied 3x with x

$\\ \rm\Rrightarrow (x^2-3x+2)(x+1)$

$\\ \rm\Rrightarrow x(x^2-3x+2)+x^2-3x+2$

$\\ \rm\Rrightarrow x^3-3x^2+2x+x^2-3x+2$

$\\ \rm\Rrightarrow x^3-2x^2-x+2$

Jose asks his friends to guess the higher of two grades he received on his math tests. He gives them two hints. The difference o

denis23 [38]

Option D. 96 is the correct answer.

Explanation:

Let the higher grade be = x

Let the lower grade be = y

As given, The difference of the two grades is 16

$x-y=16$ or $x=16+y$ .... (1)

The sum of one-eighth of the higher grade and one-half of the lower grade is 52.

$\frac{1x}{8}+\frac{1y}{2}=52$ ... (2)

Putting the value of x=16+y in equation (2)

$\frac{16+y}{8}+\frac{y}{2}=52$

$\frac{16+y+4y}{8}=52$

$\frac{16+5y}{8}=52$

$16+5y=416$

$5y=400$

$y=80$

As x=16+y

x=16+80 = 96

Hence, higher grade is 96.

In the figure, mAB = 45° and mCD = 23°. The diagram is not drawn to scale.

Yakvenalex [24]

Answer:

Option A. $x=34\°$

Step-by-step explanation:

we know that

The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite.

$x=\frac{1}{2}(arc\ CD+arc\ AB)$

substitute the values

$x=\frac{1}{2}(23\°+45\°)$

$x=34\°$
