Answer:
x = 27
Step-by-step explanation:
To find the value of x, create a proportion. A proportion is two equal ratios for similar figures. The two triangles are similar because they are the same shape but not the same size. Create ratios between corresponding sides of figures.
To solve for x, cross multiply:
(x+8)(14) = (10)(2x-5)
14x + 112 = 20x -50
112 = 6x - 50
162 = 6x
27 = x
Answer:
Step-by-step explanation: 3²+12²=x² simplifies to 9+144=x² so 153=x² or x²=153.
Y= (5x - 2) (x - 5) in standard form should be Y= 5x^2 -27x +10

where
b is the length side of the cube
In this problem we have
substitute
Answer: you can use take out the 5 and multiply 5 by 120=600.then take out the 6 and multiply 6 by 120=720.then take 600 and 720,put it into a fraction.
