8 3/4= 35/4, 2 1/2= 5/2 or 10/4, and 5 1/4= 21/4
Now multiply 35/4 by 10/4 and you get 350/16 but in simplest form it would be 175/8. Multiply that by 21/4 and you get 3,675/32 and change that into a mixed number. The answer would be 114 27/32

Prove that 1+cosA/sinA + sinA/1+cosA=2cosecA
Alla [95]
\frac{1+cos\alpha}{sin\alpha}+\frac{sin\alpha}{1+cos\alpha}=2cosec\alpha\\\\L=\frac{(1+cos\alpha)(1+cos\alpha)+sin\alpha\cdot sin\alpha}{sin\alpha(1+cos\alpha)}=\frac{1+2cos\alpha+cos^2\alpha+sin^2\alpha}{sin\alpha(1+cos\alpha)}\\\\=\frac{1+2cos\alpha+1}{sin\alpha(1+cos\alpha)}=\frac{2+2cos\alpha}{sin\alpha(1+cos\alpha)}=\frac{2(1+cos\alpha)}{sin\alpha(1+cos\alpha)}\\\\=\frac{2}{sin\alpha}=2\cdot\frac{1}{sin\alpha}=2cosec\alpha=R

Explain the difference in the solutions of linear inequalities and the solutions of systems of linear inequalities.
adoni [48]
Linear Equation

A linear equation is any equation involving one or two variables whose exponents are one. In the case of one variable, one solution exists for the equation. For example, with 2x = 6, x can only be 3.

Linear Inequalities

A linear inequality is any statement involving one or two variables whose exponents are one, where inequality rather than equality is the center of focus
