Answer:
this is a right angled triangle
so by the Pythagoras theorem
h2 = √ p2+. b2
h2 = √2 square + 6 square
h2 = 4+ 36
h2 = 40
h = √40
h = 20
Degrees Fahrenheit = (1.8 * -35) +32

Answer:
(5x+1)-(-10x+6)
Step-by-step explanation:
Since there is a negative in front of a parenthesis , multiply by -1. It would be 5×+1+10x-6. Add like terms, it would be 15x-5
George is 3 years old
Step-by-step explanation:
Three times Heidi's age plus two times Georges age equals 51
Heidi's age is also five times George's age
Assume that George's age is x
- Heidi's age is also five times George's age
- Heidi's age is 5x
- Three times Heidi's age plus two times Georges age equals 51
- 3(5x) + 2(x) is 51
Use the information to solve the problem
∵ 3(5x) + 2(x) = 51
- Simplify it
∴ 15x + 2x = 51
∴ 17x = 51
- Divide both sides by 17
∴ x = 3
∵ x represents George's age
∵ x = 3
∴ George's age is 3 years
George is 3 years old
