Answer:

4  assignments of math

Step-by-step explanation:

Gerald can complete a math assignment in 2 hours

Gerald can complete a physics  assignment in 1 hours

Equation : 2x+y=8

where x is the number of completed math assignments

y is the number of completed science assignments.

Since we are given that he decided to leave science assignment for the next day .

So, substitute y = 0

\Rightarrow 2x+0=8

\Rightarrow x=\frac{8}{2}

\Rightarrow x=4

Hence he can complete 4 assignments of math if he decides to leave the science assignments for the next day.

Savatey [412]

Answer:

Step-by-step explanation:

(5x+1)²>(2x+2)²+(4x)²

25x²+10x+1>4x²+8x+4+16x²

5x²+2x-3>0

5x²+5x-3x-3>0

5x(x+1)-3(x+1)>0

(x+1)(5x-3)>0

x+1=0,gives x=-1

5x-3=0,gives x=3/5

x >0(because 4x should be >0)

side is always positive.

so x>3/5

again 5x+1<2x+2+4x

5x-6x<2-1

-x<1

x>-1

x=all real values >3/5
