Answer:

Infinitely many solutions

Step-by-step explanation:

=> -16x - 20y = 16 => - 4(4x + 5y) = 12

=> 4x + 5y = 12/(-4) => 4x + 5y = -3 .. (1)

=> 8x + 10y = - 6 => 2(4x + 5y) = - 6

=> 4x + 5y = -6/2 => 4x + 5y = - 3 ...(2)

Note that both the equations come out be same on simplification. It means, we are given with only 1 equation that is 4x + 5y = -3, and since there is nothing more about this, equation would give different values of y for infinitely many random values of x.

Thus, 

Equation has infinitely many solutions.

Answer:

$x\sqrt{1-x}+5\sqrt{1-x}$

Step-by-step explanation:

$(x+5)(\sqrt{1-x} )\\\\=\left(\sqrt{1-x}\right)\left(x+5\right)\\\\\mathrm{Apply\:the\:distributive\:law}:\quad \:a\left(b+c\right)=ab+ac\\\\a=\left(\sqrt{1-x}\right),\:b=x,\:c=5\\\\=\left(\sqrt{1-x}\right)x+\left(\sqrt{1-x}\right)\times\:5\\\\=x\left(\sqrt{1-x}\right)+5\left(\sqrt{1-x}\right)\\\\\mathrm{Remove\:parentheses}:\quad \left(a\right)=a\\\\=x\sqrt{1-x}+5\sqrt{1-x}$

WILL GIVE BRAINLST HAVE A GOOD DAY

Sedbober [7]

1st one 17/100 2nd one 0.25

Because 0.17 would be like 17% out of 100% so the fraction simplified is 17/100

2. Since the area of a square is length×length
But according to the question we are asked to find the length and the area is given so we will have to solve this
L×L= area
L^2=0.25
Square root both sides
L=√0.25
L=0.5
Therefore the length of the square is 0.5
