Find the missing sides
a) 41
b) 6.2
c) 6.4
d) 9

c) 6.4

Step-by-step explanation:

We can use the Pythagorean theorem

a^2 + b^2 =c^2

4^2 + 5^2 = c^2

16+25 = c^2

41 = c^2

Take the square root of each side

sqrt(41) = sqrt(c^2)

c = 6.403

the answer is 14ft

step-by-step explanation:

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
