I believe it'd be -x - 18 you'd add the 12x and 2x and get 14x-15x and get -x then you'd combine the -15 and -3 to get -18.
B, there's only two kinds of acute triangles ands that's a 45,45,90 and a 30,60,90.
Answer:
d
Step-by-step explanation:
yes
0.0394736842 is the answer
Write 76 <span>)¯3¯¯
</span>
add a 0 next to the 3 ( you will have 30) then on top of the divison bar put a "." one space over the 3 so like
0.
76<span>)¯30¯¯ (lol)
since 76 still cant go into the 3 add another 0 to the 30 ( so you should now have 300) and a 0 next to the "." so you have 0.0 on top.
76 goes into 300 3 times wich is with a reminder of 72. (76x 300 is 228)
write a 3 next to the 0.0 so you have 0.03
write 228 under the 300
subtract. you get 72
write the 72
since 76 cant go into 72 add a 0 to the 300. Drop the 0 to the 72 so you have 720.
I think you can figure out the rest. If not tellme and I will do the next step and you can take it from there

The <em>approximate</em> solution of the equation shown in the picture is x ≈ 39 / 8 (Right choice: B).
<h3>How to find an approximate solution of a one-variable equation</h3>
The solution of the equation is between x = 4 and x = 5. Now we begin by evaluating each side of the expression (f(x) = x² - 5 · x + 4, g(x) = 2 / (x - 1)) at the average of x = 4 and x = 5.
x = (4 + 5) / 2
x = 4.5
f(4.5) = 4.5² - 5 · 4.5 + 1
f(4.5) = - 5 / 4
g(4.5) = 2 / (4.5 - 1)
g(4.5) = 4 / 7
The solution of the equation is between x = 4.5 and x = 5, then we evaluate at the average:
x = (4.5 + 5) / 2
x = 4.75
f(4.75) = 4.75² - 5 · 4.75 + 1
f(4.75) = - 3 / 16
g(4.75) = 2 / (4.75 - 1)
g(4.75) = 8 / 15
The solution of the equation is between x = 4.75 and x = 5, then we evaluate at the average:
x = (4.75 + 5) / 2
x = 4.875
f(4.875) = 4.875² - 5 · 4.875 + 1
f(4.875) = 25 / 64
g(4.875) = 2 / (4.875 - 1)
g(4.875) = 16 / 31
The <em>approximate</em> solution of the equation shown in the picture is x ≈ 39 / 8 (Right choice: B).
