Answer:
Step-by-step explanation:
A fraction is in its simplest form if its numerator and denominator have no common factors other than 1.
36/1
Answer:
s = 3
Step-by-step explanation:
we know the rectangles are similar
2 × __ = 16
s × __ = 24
so,
16÷2 = 8
2 × 8 =16
s × 8 =24
then,
24 ÷ 8 = s
3 = s
2 × 8 = 16
3 × 8 =24
hoped i helped :)
X = 40 min
y = 10 min
x = 40/60 h --> x = 4/6 h --> x = 2/3 h
y = 10/60 h --> y = 1/6 h
x + y = 2/3 - 1/6
x+y = 4/6 - 1/6
x+y = 3/6 h = 3*60'/6 = 3*10 = 30 min

Answer:</h3>
- -100x +100; 3
- 5x +81; 162
<h3>
Step-by-step explanation:</h3>
The distributive property is your friend. It tells you ...
a(b + c) = ab + ac
It can also be used to simplify the product of binomials (or other polynomials).
(a +b)^2 = (a +b)(a +b) = a(a +b) + b(a +b) = a^2 +ab +ab +b^2
(a +b)^2 = a^2 +2ab + b^2 . . . . . . . worth remembering
1. (x -10)^2 -x(x +80) = (x^2 -20x +100) +(-x^2 -80x)
= -100x +100 . . . . . . simplified form
For the purposes of calculation, it can be easier to factor out 100:
= 100 (1 -x)
Then for x = 0.97
= 100(1 -0.97) = 100(0.03) = 3
___
2. (2x +9)^2 -x(4x +31) = (4x^2 +36x +81) -4x^2 -31x = 5x +81
For x = 16.2, this is ...
5(16.2) +81 = 81 +81 = 162
