Step-by-step explanation:
(ax + b)² = a²x² + 2abx + b²
In this case, a = 1, so:
14 = 2b
b = 7
(x + 7)² = x² + 14x + 49
The answer to the question
Answer:
<h2>A) Height is the missing measurment.</h2><h2 /><h2> B) 1,400= 20 × 14 × H</h2><h2 /><h2>C) 1400 ÷ H = 280</h2>
Step-by-step explanation:
A) Length × Width × Height
B) V is 1,400
L is 20
W is 14
H is unknown so use a variable
C) 20 × 14= 280.
1a+-1+a I believe that would be the answer
