w=37
2w+w+69= 180 knowing that all triangles add up to 180 form an equation
3w+69=180 combine like terms and subtract 69 from both sides
3w=111 divide by 3 from both sides
w=37
The answer is C. Hope you get it!
672 cm³
Step-by-step explanation:
10x7x9=630
2x3x7=42
630+42=672
Answer: 2
Step-by-step explanation:
square root means that you divide a number by the prime factorization, in this case you take 4 and divide it by the number that is multiplied twice to get that number, ex. 3*3 or 2*2
In this exercise we have to use the knowledge of geometric progression to find three specific numbers, in this way we can say that these numbers correspond to;
Then using the formula of the geometric progression we find that:
now, the differences between the terms must be the same:
and now, when we increase the third term by 9,so we have:

Now we use that identity in the first equation :
The general solution for a quadratic equation is
We have that:
so, put the numbers in the formula we find:
