Here, angle (3x-1) is supplementary with 5x, so their sum would be equal to 180
3x - 1 + 5x = 180
8x = 180 + 1
x = 181/8
x = 22.625
Hope this helps!
Answer: (-3, -21)
I'm not sure if that's what you wanted, sorry.
Okay. So, using the scale, we can solve for the length of the actual boat by writing and solving a proportion. Let’s write it out like this: 1/6.5 = 7.5/x. This is because you’re looking for the real length of the boat, so the x would be lined up horizontally with 6.5, as shown in the proportion. Let’s cross multiply. 6.5 * 7.5 is 48.75. 1 * x is 1x. 48.75 = 1x. Now, let’s divide each side by 1 to isolate the “x”. When you do that, you get x = 48.75. There. The length of the actual boat is 48.75 feet.
The answer to your question is:
<span>there are holes at x= 3/2 and x=-1/3</span>
Hello! And thank you for your question!
First we are going to expand the equation:
<span>−2<span>m^<span><span>2</span><span></span></span></span>−2mn+8m−10m+10n+nm+4<span>n<span><span>^2</span><span></span></span></span>−5n
Then we are going to combine like terms:
</span><span><span>−2<span>m<span><span>^2</span><span></span></span></span>+(−2mn+mn)+(8m−10m)+(10n−5n)+4<span>n<span><span>^2</span><span></span></span></span></span>
</span>
Then finally, simplify:
−2<span>m<span><span>^2</span><span></span></span></span>−mn−2m+5n+4<span>n<span>^<span>2
Final Answer:
</span></span></span>
−2m^2−mn−2m+5n+4n^2
