Answer B is the correct answer ;p
To find x, first we'll split the triangle in two right triangles.
The first triangle will be the one with sides (8,x+4,y) and the second triangle will be the one with sides (12,2x+1,y).
As you can see, these two triangles share the side 'y'.
To solve we'll do the following; first solve for 'y' by applying the Pythagorean theorem in the second triangle, and finally solve for 'x' applying Pythagorean theorem in the first triangle.
From the second triangle (12,2x+1,y) we solve for 'y' by writing:

Now that we know 'y^2' we apply Pythagorean Theorem in the first triangle (8,x+4,y)


Now you solve the quadratic equation, you'll get a positive and negative value; as this are lengths, you take the positive and get:
4/7 is not equal to 8/12. It is not equal because if you 4x2= 8 is equal but if you do 7x?= 12 it would be a decimal and you need equal numbers to make it a equivalent fraction. If it was 4/7= 8/14 that would be equivalent.
Hope I helped! : -)
Answer:
Step-by-step explanation:
2^6 because
2 times 2 times 2 times 2 times 2 times 2 is 64
2 times 2 is 4 times 2 is 8 times 2 is 16 times 2 is 32 times 2 is 64
Answer:
-3
Step-by-step explanation:
The slope formula is y2-y1/x2-x1, so replace the variables with the given values.
-5-5/1-x= -5/2, now multiply both sides by "1-x"
-5-5= -5/2(1-x) or -10=-5/2+5/2x, now add 5/2 to both sides
-20/2+5/2=5/2x, now simplify the equation
-15/2=5/2x, multiply both sides by 2/5
-30/10=x or x is -3
