Let garret’s age be x
x + 2 + (x + 3) + 2 = 39
2x + 7 = 39
2x = 32
x = 32/2
x = 16
Garrett’s age after two years = 16 + 2 = 18
D.y = 10x + 250
y = 12x + 150 is the correct answer to the question
Answer:
a=15
Step-by-step explanation:
By pythagoras' theorem
25²=20²+a²
625=400+a² group like terms
a²=625-400
a²=225

therefore a=15
FORMULA:
TSA of cubes = 6(a)²
ANSWER:
We just have to plug the respective value.
So, TSA of 8 cubes = 6 × (12)²
So, <u>Correct choice</u> - [C] 864 ft².
