160 cm because if I am correct, then two of the sides are labeled as 10 cm. Which means that they are both the same measurement.
Step-by-step explanation:
a = 2i + j - k
b = -1 -7j + k
a × b = (2i + j - k) (-1 + 7j + k)
-2i + 14ij + 2ik - j + 7j^2 + jk + k -7jk - k^2
-2i + 14ij + 2ik -j +7j^2 +jk - 7jk + k - k^2
-2i + 14ij + 2ik - j +7j^2 - 6jk + k - k^2
Answer: -209
Step-by-step explanation:
Formula for arithmetic progression
= a + (n - 1)d
Since a10 = 1 and d = -6
a10 = a + 9d
a + 9(-6) = 1
a - 54 = 1
a = 1 + 54
a = 55
Therefore, 45th term = a + (n - 1)d
= a + (45 - 1)d
= a + 44d
= 55 + 44(-6)
= 55 - 264
= -209
The standard form of any linear equation with two variables is

, where a, b, and c are constants. To convert this equation to standard form, simply subtract

from both sides to get

We could leave it in this form, though, in this case, it might be better at if we multiplied both sides by -1 to get
Answer:

Step-by-step explanation:
Given that,
He makes $10 per hour making sandwiches, and $14 per hour delivering orders.
Let there are s sandwiches and d is delivering orders.
Eric puts half of his total earnings in a savings account for college.
The expression that represents the total amount of money Eric saves for working s hours making sandwiches and d hours delivering orders.

Hence, this is the required solution.
