Answer:
The correct answer is 8x^2+28x+20.
Step-by-step explanation:
(2x+5)(4x+4)
Multiply the first bracket with each element of second bracket:
=4x(2x+5)+4(2x+5)
=8x^2+20x+8x+20
Now solve the like terms:
=8x^2+28x+20
Thus the correct answer is 8x^2+28x+20....
Answer:
the answer is 12
Step-by-step explanation:

21 because a triangle is always going to equal 180 so add those then subtract and it’s 21
Answer: 14.7338936% decrease

cross-multiply
85.2661064 = x
100 - 85.2661064 = 14.7338936
Check: 0.852661064 * 5355 = 4566
If permitted, you may round for a simpler (yet less precise and exact) answer. For instance, rounding to the hundredths would make it ~14.73%.
