C because the 2 is a single term, the 4x is a single term, and the 7y is a single term.
X^2 + 8x - 5 = 0
a = 1, b = 8, c = -5
x = ( - 8 + - sqrt(64 - 4*1*-5))/2
x = ( -8 + - sqrt(64+20))/2
x = ( -8 + - sqrt (84))/2
x = ( - 8 + - 2sqrt21))/2
x = -4 + - sqrt21
Answer:
x=9.73
Step-by-step explanation:
This is trigonometry work! :)
So cos46°=x/14
x=14×cos46°
x≈9.73
Hope this helps <3

Hi my lil bunny!
❀ _____.______❀_______._____ ❀
Let's solve your equation step-by-step.
![(\frac{2}{3}x) ( \frac{-6}{7} + \frac{4}{5}) = [\frac{\frac{2^x4}{3} }{5} ] ( \frac{-6}{7} )](https://tex.z-dn.net/?f=%28%5Cfrac%7B2%7D%7B3%7Dx%29%20%28%20%5Cfrac%7B-6%7D%7B7%7D%20%2B%20%5Cfrac%7B4%7D%7B5%7D%29%20%3D%20%5B%5Cfrac%7B%5Cfrac%7B2%5Ex4%7D%7B3%7D%20%7D%7B5%7D%20%5D%20%28%20%5Cfrac%7B-6%7D%7B7%7D%20%29)
Step 1: Subtract 
from both sides.
Step 2: Factor left side of equation.
Step 3: Set factors equal to 0.
So the answer is : x = 0 or x = - 0.759836 or x = 0.759836

Answer:
(-2.5, 7.5)
Step-by-step explanation:
Find the coordinates of the point P that divides the directed line segment from A to B in the given ratio. A(−9, −1), B(11, 9); 3 to 2
Using the formula for calculating the mid point segment expressed as;
X = ax1+bx2/a+b
Y = ay1+by2/a+b
Given
x1 = -9, y1 = -1, x2 = 11, y2 = 9, a = 3 and b = 2
Substitute
X = 3(-9)+2(11)/2
X = -27+22/2
X = -5/2
X = -2.5
Similarly
Y = 3(-1)+2(9)/2
Y = -3+18/2
Y = 15/2
Y = 7.5
Hence the required coordinate point is (-2.5, 7.5)
