- Completing the Square: b/2a
Step-by-step explanation:
<u>Step 1: Define expression</u>
x² + 8x - 5 = 15
<u>Step 2: Solve</u>
- Isolate <em>x</em> terms: x² + 8x = 20
- Complete the Square: (x² + 8x + 16) = 20 + 16
- Simplify: (x + 4)² = 36
13 cm
Explanation:-
I'm not so sure, but I hope this is the answer.
Given, SR=39cm
To find WX
As WX is parallel to Sr, WX is half of SR


Answer:
See below
Step-by-step explanation:
a) 43.8 - 38 = 5.8 yrs
b) SD = 8.9 yrs 5.8 / 8.9 = .6517 SD <u> below</u> the mean
(A z score merely shows how many standard deviations a score (age) is above or below the mean in SD units)
c) Z = - .6517 Negative because it is <u>BELOW</u> the mean ( FYI from z-score table: this is .2578 in percentage )
d) usual ( it (-.6517) is between -2 and + 2 )
Answer:
∠LMN = 167°
Step-by-step explanation:
∠LMT = 23°
∠TMN = 144°
∠LMN = ∠LMT + ∠TMN
∠LMN = 23° + 144°
∠LMN = 167°
