We are asked to find a range for x. Let's start by finding the maximum value. We know, by definition, that a side opposite a larger angle has a longer length. For example, if you think about a right triangle, the hypotenuse (the longest side) is always opposite of the right angle (the largest angle). We are given two side lengths: 23 is opposite of 42 degrees, and 21 is opposite of 3x + 15. Because 42 is opposite the longer side, 42 degrees is a larger angle than 3x + 15. We can set up the inequality and solve for x:

Now, let's look at the minimum value. We know that the angle definitely has to be larger than 0. So, we can set up that inequality and solve for x:

Now, we have our final range: -5 < x < 9
Idk math but I can sell come thru for that low
Answer:
f(-1)=(-1)²+-1=1-1=0
i think it is your answer
Step-by-step explanation:
(7x - 5x) -3 =x+4
2x - 3 = 2x + 7
