Answer:
Step-by-step explanation:
Lets factor the trinomial 
step-by-step:
Step 1. Since all the terms are negative, we can factor -1 out
Step 2. Split the middle term of 
, so 
Step 3. Group common terms
Step 4. Factor each parentheses
Step 5. Factor the common binomial
Now, we can put it all together:
Answer:
<h2>138°</h2><h2 />
Step-by-step explanation:
∡5 = 42°
find: ∡ 14
solution:
since ∡5 = ∡13 = 42°
∡14 = 180 - ∡13
= 180 - 42
= 138°
Y - 8 = -7 (x + 3)
this is in point slope form
y - 8 = -7x - 21
y = -7x - 13
this is slope intercept form
Step-by-step explanation:
When w=10, 7w=7×10=70
But the given value of 7w is 73.
So, the given value is not a solution of the equation.
