Answer:
Step-by-step explanation:
for right-angled triangle: a^2 + b^2 = c^2
given a = 5 n b = 10
c^2 = 5^2 + 10^2
= 25 + 100
= 125
c = sqrt(125)
= 5*sqrt(5)
2+12a. When adding, you're only collecting "like terms".
The side b = 136 as I think it’s the two equal sides
Question 1: you would divide 13 from both sides of the equation, making the answer w = 3
Question 2 : you would divide 11 from both sides of the equation, making the answer x = 5
Question 3: the answer is already there, it's r = 5
Answer: -25
Since x=-3, y=6, and z=-4 you have to plug those numbers into the corresponding varibale in the equation. So 3x becomes 3(-3) because x=-3, 2y becomes 2(6) because y=6 and z becomes just -4. The whole equation comes to 3(-3)- 2(6)+(-4)= -25
