Step-by-step explanation:
Answer:
Option D. It's a perfect square trinomial.
Step-by-step explanation:
(a) 36x² - 4x + 16
= (6x)² - 2(2x) + (4)²
It's not a perfect square trinomial
(b) 16x² - 8x + 36
= (4x)² - 2x(4x) + (6)²
It's not a perfect square trinomial
(c) 25x² + 9x + 4
= (5x)² + 2
+ (2)²
It's not a perfect square trinomial
(d) 4x² + 20x + 25
= (2x)² + 2(10x) + (5)²
= (2x+5)²
It's a perfect square trinomial.
Answer:
divide 11 into 8 and 3 whose product is 24
The area of a square is s•s.
A= 6.25•6.25
A= 39.0625
Rounded= 39.06 square feet
(I'm assuming rounding to the significant digits means rounding to the hundredths since 6.25 is rounded to the hundredths.)
4 3/4 - 2 = 2 3/4
2 3/4 - 1 1/10 is the same as 2 30/40 - 1 4/40 = 1 26/40
1 26/40 = 1 13/20 pounds left
