Answer: 4
Step-by-step explanation: 1/4w + 1/4w + w + w = 10
2/4w + 2w = 10
1/2w + 2w = 10
2.5w = 10
Divide 10 by 2.5
width = 4
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!
