Answer:

Step-by-step explanation:
In this problem, we are expected to write/express the given statement in algebra notation. that is using mathematical expression letters and symbols to express word problem
Hence: nine times the difference of 5 and y
1. the difference of 5 and y= (5-y)
2. 9*(5-y)
Hence the expression is given as 
10. GCF is 3
11. GCF is 4
12. GCF is 16
13. That the numbers are prime
:)
Answer:
None of the above, f(5) + g(-3) = 19.
Step-by-step explanation:
Given f(x)=2x+4 and g(x)=x2−4, determine the value of (5) + (−3). Assume that is supposed to be f(5) + g(-3).
f(5) + g(-3) = 2×5 + 4 + (-3)^2 - 4
= 10 + 4 - 4 + (-1)^2(3)^2
= 19
Answer:
True
Step-by-step explanation:
If the triangle was a right angled triangle then we can prove it using the Pythagoras theorem: c² = a² + b²
c is the largest side and a and b are the two smaller sides of the triangle.
So if this is true then √72² + 154² should be 170:
170² = 72² + 154²
28900 = 5184 + 23716
28900 = 28900
So we have proved using Pythagoras theorem that the triangle is a right angled triangle.
