Answer:
b
Step-by-step explanation:
the answer is v simpldhdjdj
Step-by-step explanation:
step 1. there are 3 right triangles!
step 2. 8/6 = 6/x (definition of right triangle with an altitude)
step 3. 8x = 36 (cross multitude)
step 4. x = 9/2 (divide both sides by 8)
step 5. 6^2 + x^2 = y^2 (pythagorean theorem)
step 6. 6^2 + (9/2)^2 = y^2
step 7. 144/4 + 81/4 = y^2
step 8. 225/4 =y^2
step 9. y = 15/2 = 7.5.
B)(x+10).(x-6)=x²-6x+10x-60
x²+4x-60
C)(x+15).(x-4)=x²-4x+15x-60
x²+11x-60
D)(x+20).(x-3)=x²-3x+20x-60
x²+17x-60
But A,
(x+12)(x-5)=x²-5x+12x-60
x²+7x-60
A, is the correct answer..
GOOD LUCK!
1,521 millileters is equal to 15.21 deciliters.
In a deciliter, there are 100 milliliters. So, for this problem you would divide 1,521 by 100 to find the equality of milliliters to decimeters. Solving this, would give you 15.21 decimeters.
I hope this helps!!
Ok i) The equation for a slope is y= mx + c where m is the gradient and c the y-intercept. Ok so the gradient is the y rise / x run. You have selected -2 to 4. The rise is -2 and the run is 4. -2 / 4 = -0.5. So y = -0.5x - 2
ii) (0, -2)
iii) I think this one number i). Ill do i) here, -0.5
