Answer:
B
Step-by-step explanation:
p(x) = r(x) * s(x)
= (x + 5) *(-7) {Use distributive property}
= x * -7 + 5 * -7
= - 7x - 35
A={2,3,5}
B={1,3,4}
A∩B={3}
R: a. {3}
Answer:
a= c/2
b= (c/2)×√3
side b is the side with the 60 degree angle.
side a is the side with the 30 degree angle.
using the theorem that the side with the 60 degree × 2 = length of side c and the side with the 60 degree × √3 = b.
I get the following equations shown above.
