i think the answer is _>
Step-by-step explanation:
where is the x ?
Answer:
every 5 minutes ....
Step-by-step explanation:
Set two of the sides equal to one another:
8x - 20 = 4x + 18
4x = 38
x = 38/4
x = 19/2 or 9.5
now that we know x, plug it back in to find the side lengths:
4(9.5)+ 18 = 38 + 18 = 56
that is your side length
since it’s equilateral, the perimeter is equal to
56 x 3
final answer: 168
hope this helps:)
To factor out x2 + bx + 16, the easiest way is to find out 2 different values that will add up to b but when multiplied is positive 16. Given that the only solution to this equation above is x = 4. the factored out form should be (x - 4)^2 or (x-4)(x-4). As b should be the addition of these two x values, b should be -8. The correct option is the second option, b = -8.
