Step-by-step explanation:

seen that before

second question-heres answer

v20

convert v20 to a decimal 4.4721...

find the number in the hundredth place 7 and look one place to the right for the rounding digit 2.round up if this number is greater than or equal to 5 and round down if it less than 5

4.47

answer:  

123455421

step-by-step explanation: easy

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
