Answer:
13
Step-by-step explanation:
We know that a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
5^2 + 12^2 = c^2
25+144 = c^2
169 = c^2
Taking the square root of each side
sqrt(169) = sqrt(c^2)
13 =c
Answer:
209.25 ft²
Step-by-step explanation:
2.7cm * 5 = 13.5 ft
3.1cm * 5 = 15.5 ft
Area
a = 13.5 * 15.5
a = 209.25 ft²
Answer:
<u>(x² + 4x + 6)/ 3x + 12</u>
<u>This is the most simplified form</u>
Step-by-step explanation:
Let's simplify the expression:
(x + 6)/(x + 4) + (x - 3)/3
Least Common Denominator : 3 * (x + 4)
[3 * (x + 6) + (x - 3) (x + 4)]/ 3 * (x + 4)
Solving parentheses:
[3x + 18 + x² - 3x + 4x - 12]/ 3 * (x + 4)
Like terms:
<u>(x² + 4x + 6)/ 3x + 12</u>
<u>This is the most simplified form</u>
Answer:a=3/4
b=3/4
Step-by-step explanation:
3a+5b=6
9a+7b=12
-3(3a+5b)=-3(6)
9a+7b=12
-9a-15b=-18
9a+7b=12
-8b=-6
b=3/4
3a+5(3/4)=6
3a+15/4=6
3a=9/4
a=3/4
