Factor the expression:
16y-8

8 (2y-1)

Step-by-step explanation: first start by writing like this below:

16y-8

Then factorise the numbers(cut the numbers)

2×2×2×2×y - 2×2×2

Now take all which is common like:

2×2×2=8

Then,take the remained numbers and add it into the brackets.

8 (2y - 1) Here, why we should put 1,because there's nothing left.

If you want to check the answer, factorise this expression and see:

8 (2y-1)

16y-8.

Hope it helps you!!

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

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
