Step-by-step explanation:
To verify cos²A + sin²A = 1 with A = 90° , then
cos²90° + sin²90°
= (0)² + (1)²
= 0 + 1
= 1
Answer:
C
Step-by-step explanation:
193b=212.3
193b/193=212.3/193
(divide by 193 to get the value of b)
193 cancels 193
b= 1.098445596
(round off to one decimal place)
b=1.1

3/7 = 9/x
cross multiply because thats how u solve proportions
(3)(x) = (7)(9)
3x = 63
x = 63/3
x = 21
and if u will notice : 3/7 and 9/21 ....9/21 reduces to 3/7....so these are equivalent fractions...because proportions are nothing but equivalent fractions
Answer:
<h2>-4x + 9x</h2>
Step-by-step explanation:
Combine like terms:
-4x - 9x = (-4 - 9)x = -13x
4x - (-9x) = 4x + 9x = (4 + 9)x = 13x
-4x + 9x = (-4 + 9)x = <u>5</u>x
4x - 9x = (4 - 9)x = -5x
