we are given with a triangle with the sides 6 ft, 21 ft, 23 ft. although it follows the rule of triangles that state that no side of the triangle exceeds the sum of the lengths of two other sides, this does not follow Pythagorean theorem: 23^2-21^2 = 88 which is not equal to 6^2 or 36. This is not a right triangle, hence. Hope this helps!
-3x + y - 2z = 10 |* -1
3x - y +2z = -10
5x -2y -2z = 12
--------------------------- I add these equations term by term
8x - 3y = 2
-3x + y - 2z =10 ⇒ -3x + y - 2z =10
x -y +z = 23 | *2 2x - 2y + 2z = 46
----------------------------- I add these eq.
-x -y = 56
8x - 3y = 2
-x -y = 56
this is the system after i reduce it ( it has only two variables x and y)
Answer:
360cm
Step-by-step explanation:
The top square is 10 x 13 = 130
The middle square is 10 x 12 = 120
Both side triangles are 5 x 12 = 60. You would halve it but there are two triangles.
5 x 10 = 50
50 + 120 = 170
170 + 130 = 300
300 + 60 = 360
Equation would be (10 x 13) + (10 x 12) + (5 x 12/2) + (5 x 12/2) + (10 x 5)
The equation options seem like they are missing some numbers or something
Answer:
b=6
Step-by-step explanation:
9/b=21/14
9/b=3/2
9=3/2b
9=3b/2
9×2=3b
18=3b
18/3=b
6=b
b=6
Answer:
A) f(n) = 12 + 2(n-1)
Step-by-step explanation:
Arithmetic Sequence Formula:
a(n) = a(1) + (n-1)d
d = 2
a(1) = 12
a(n) = 12 + 2(n-1)
