In order to get an 81 average,
the student has to get 81x5=405
71+96+90+73+?=405
330+?=405
405-330=75
he needs to get an 75
Answer:

Step-by-step explanation:
Answer:
-x² + 16x - 60
Step-by-step explanation:
Given expression:
Step 1. <u>Insert</u> brackets to isolate the "-" from the (x - 8)².
⇒ -(x - 8)² + 4
⇒ -[(x - 8)²] + 4
Step 2. <u>Use</u> the formula (a - b)² = a² - 2ab + b²
⇒ -[(x - 8)²] + 4
⇒ -[x² - 2(x)(8) + 8²] + 4
Step 3. <u>Open</u> the parenthesis
⇒ -[x² - 2(x)(8) + 8²] + 4
⇒ -x² + 2(x)(8) - 8² + 4
Step 4. <u>Simplify</u> as needed
⇒ -x² + 16(x) - 64 + 4
⇒ -x² + 16x - 60
Answer:

Step-by-step explanation:
<u>Given:</u>
∠N = ∠K = 90°
LM bisects ∠KLN such that ∠KLM ≅ ∠NLM
<u>To prove:</u>
ΔKLM ≅ ΔNLM
<u>Proof:</u>
<u>Statements</u> | <u>Reasons</u>
ΔKLM ↔ ΔNLM |
∠N ≅ ∠K | Given (Both equal to 90°)
∠KLM ≅ ∠NLM | Given (Bisected Angles)
LM ≅ LM | Common
ΔKLM ≅ ΔNLM | A.A.S Postulate
