They would be 69 and 70.
Your equation would be x + (x + 1) = 139
X would be the first integer and x + 1 would be the second
You would then solve the equation to get x as 69
X + 1 would then be 70
187 centimeters is 1.87 meters
Answer:
4 is the square root of 2 and it's less than 9
Answer:
There is something called "criteria of congruence for triangles".
Those criteria say that, with some data of the triangles, we can know if the triangles are equivalent.
For example one of the criteria is SSS.
Side-side-side.
This means that all the triangles with equal side length for all their sides are equivalent.
So if the information that we give to the factory is the side length of the 3 sides of the triangle, the triangle will be well defined.
Following those criteria, the other 2 options can be:
SAS
Side-Angle-Side
(so you can give the length of two sides and the angle between them)
ASA
Angle-Side-Angle.
(You can give the value of two angles and the length of the side between those two angles)
Answer:
<u>-53</u>, f(n) = -6(n-1) + 13
Step-by-step explanation:
given the equation to this linear/arithmetic sequence for the nth term: f(n) = -6(n-1) + 13
f(12) = -6(12-1) + 13
f(12) = -6(11) + 13
f(12) = -66 + 13
f(12) = -53
*substitute and simplify*
______________
f(n) = f(1) + d(n-1)
given f(1) = 13, f(2) = 7, and f(3) = 1
7-13 = 1-7 = <u>-6</u> = d
= f(1) + d(n-1)
f(1) = <u>13</u> so
the equation must be f(n) = <u>13</u> <u>-</u><u> </u><u>6</u>(n-1) or -6(n-1) + 13
