1: B
because a triangle angles all have to add up to 180
Answer:
2z + 12y - 32
Step-by-step explanation:
1) 2z cannot be combined with any other number because no other number has the variable z.
2) 4y and 8y are both positive and van be combined. Therefore, it is 12y.
3) -32 cannot be combined with any other number because it doesn't have a variable that is the same as the others.
Therefore, the answer is 2z + 12y - 32
No need for Brainliest on these easy ones. The perimeter is the sum of all four sides, so
P = 6 + 4 + 6 + 4
Answer: P = 6 + 4 + 6 + 4, first choice
1/4, 3/8, 1/2, 5/8, 3/4
Those are all the major measurements in between an inch.
Answer:
2n - 11
Step-by-step explanation:
Note there is a common difference d between consecutive terms of the sequence, that is
d = - 7 - (- 9) = - 5 - (- 7) = - 7 + 9 = - 5 + 7 = 2
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 9 and d = 2, thus
= - 9 + 2(n - 1) = - 9 + 2n - 2 = 2n - 11
