Answer:
I'll help out a bit:
Step-by-step explanation:
So ANY number in a square root is irrational(Non-terminating and no pattern)
Pi is also irrational
But ANY number that can be expressed as a fraction is rational(Also Whole numbers, natural numbers, etc.)
Hope this helps!
Answer:
I think it would be 5(4b+7)
Step-by-step explanation:
I divided both terms by 5.
Answer:
Step-by-step explanation:
3. Use Cosine law to find the length of the unknown side (PR)
q² = p² + r² - 2prCos Q
q is the opposite side of ∠Q;
p is the opposite side of ∠P; p = 33
r is the opposite sides of ∠R ; r = 67
q² = 33² + 67² - 2* 33*67 Cos 19°
= 1089 + 4489 - 4422 * 0.95
= 1089 + 4489 - 4200.9
= 1377.1
q = √1377.1
q = 37.1
PR = 37.1
To find the angle use law of sin

Sin P = 0.3

P = 17.5°
∠R = 180 - (19 + 17.5)
= 143.5°
Answer:
Convex, since none of the angles are greater than 180°
7x+6=3x-6
+6 +6
7x+12=3x
-3x -3x
4x+12=0
-4x -4x
divide both sides by -4 but you have to flip the sign.
-3>x
or
{x | x < -3}
