Step-by-step explanation:

82+OCE=90°{ tangent}

0CE=8°

OCE=OEC (base angle of isosceles triangle r equal}

8+8+a=180°(sum of angle of triangle)

a=180-16

a=164°

b)d+BEC=180°

BEC=122°

BEO=BEC-OEC

114°

b=114°

Answer:

CEO=ECO=90-82

COE=180-(16)

=164

a=164

DBO=DCO=90

BOC=180-58

=122

BOE=360-(122+164)

=74

b=180-74/2

=53

Multiply (-8x - 9)(-9x2 + 7x - 9).

Misha Larkins [42]

= <span>(-8x - 9)(-9x2 + 7x - 9)

= 72x</span>³ - 56x² + 72x + 81x² - 63x + 81

= 72x³ + 25x² + 9x + 81

In short, Your Answer would be: Option D

Hope this helps!

Please help me with this

Answer:

Option c

Step-by-step explanation:

A system of equations are given to us. And we need to solve them . The given system is

$\begin{cases} y = 2x - 3\dots 1 \\ y = x^2 - 3\dots 2 \end{cases}$

We numbered the equations here . Now put the value of equation 1 in equation 2 that is substituting y = 2x - 3 in eq. 2 .

$\implies y = x^2 - 3 \\\\\implies 2x - 3 = x^2 - 3 \\\\\implies x^2 - 2x = 0 \\\\\implies x(x-2) = 0 \\\\\implies\red{ x = 0 , 2 }$

We got two values of x as 0 & 2 . Alternatively substituting these values we have ,

$\implies y = 2 x - 3 \\\\\implies y = 2(0)-3 \qquad or \qquad y = 2(2)-3 \\\\\implies y = 0-3 \qquad or \qquad 4 - 3 \\\\\implies \red{ y = -3 , 1 }$
