Okay so remember pemdas so firs multiply 3 x -7= -21 then add 10+25= 35
so a similar equation could be (-21) - 35 = - 60
PS: your first expression's answer is incorrect it's supposed to be -60
hope that this helped you (;
The answer is D.
8:200 is equivalent 1:25
(I divided 8 and 200 by 8 to get that.)
1:25 multiplied by 18 is 18:450
Answer:
Angle D is equal to 80.
Step-by-step explanation:
We know that the sides are congruent and that angle ACB is congruent to angle ECD by the vertical angles theorem.
Triangles' angles always add up to 180.
180 - 70 - 30 = 80
angle D is equal to 80.
1.) 4, 2, 1, 1/2,1/4,... 2.) 2, 6, 18, 54, 162, … 3.) <span>−4, −16, −64, −256, … are geometric sequences because common ratio is same. Example: 1.) ratio of 1st and 2nd term is 1/2. similarly ratio of 3rd and 4th term is 1/2 and so on. </span>
