Answer 1,2, and 5 are right, answers 3 and 4 are wrong.
Answer:
2(n+3)-6
n=0
Step-by-step explanation:
2(3+n)-6=
Simplifying
2(3 + n) + -6 = 0
(3 * 2 + n * 2) + -6 = 0
(6 + 2n) + -6 = 0
Reorder the terms:
6 + -6 + 2n = 0
Combine like terms: 6 + -6 = 0
0 + 2n = 0
2n = 0
Solving
2n = 0
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Divide each side by '2'.
n = 0
Simplifying
n = 0
Answer:
C
Step-by-step explanation:
Given that the 2 triangles are similar then the ratios of corresponding sides are equal.
This enables RT to be found, that is
= 
( cross- multiply )
4RT = 60 ( divide both sides by 4 )
RT = 15
Hence
perimeter of ΔRST = 6 + 12 + 15 = 33 units
Answer:
E) -4,7 and -2,8
Step-by-step explanation:
parallel lines have same slope
x - 2y = 16
y = 1/2 x -8 slope: 1/2
E. slope = Δy / Δx = (8-7) / (-2 - -4) = 1/2
Answer:
but
Step-by-step explanation:
moreover is more of a transition that means "also"
furthermore is used as a conclusion
