<span>(5x^2 + 2x + 11) − (7 + 4x − 2x^2)
= </span>5x^2 + 2x + 11 − 7 - 4x + 2x^2
= 7x^2 - 2x + 4
Answer:
see below
Step-by-step explanation:
given: size of television is height = 37 in, length = 71 in.
A. using Pythagorean theorem:
parts given are legs which is the sides
looking for the hypotenuse.
B. formula:
a² + b² = c² or H² + L² = D²
where H = height = 37
L = length = 71
D = diagonal (which is req'd)
C. D² = 37² + 71²
D = 
D = 
D = 80 in (missing length)
D. size of television:
37 x 71 in
Diagonal is 80 in
hope it helps and good luck!
