Answer:
x = -0.683 (3dp)
x = -7.317 (3dp)
Step-by-step explanation:
<u>Step 1: Apply the quadratic formula</u>
(-b±(
)) / 2a
a = 1 <em>(x²)</em>
b = 8 <em>(8x)</em>
c = 5 <em>(5)</em>
(-8±(
)) / 2 x 1
<u>Step 2: Simplify</u>
(-8±(
)) / 2
<u>Step 3: Solve</u>
You need to replace the ± with first a + and then a -.
(-8+()) / 2 = -0.683 (3dp) = x
(-8-()) / 2 = -7.317 (3dp) = x
Hope this helps!
right triangle
c^2 = a^2+b^2
30^2 = 24^2+18^2
900 = 576 +324
900 = 900

Answer:
(1/2) qt/(3/4) hr = (1/2)*(4/3) qt/hr = (2/3) qt/hr
The rule for division of fractions is: invert the denominator and multiply.
Multiply both sides by the reciprocal (-8/7). You would get 40/7 or 5.71428571
