Answer:
(8 - 12 )
Step-by-step explanation:
Given
x -
y = 8
x +
y = - 5
Multiply both equations through by 4 to clear the fractions
x - 2y = 32 → (1)
2x + 3y = - 20 → (2)
Multiplying (1) by - 2 and adding to (2) will eliminate the x- term
- 2x + 4y = - 64 → (3)
Add (2) and (3) term by term to eliminate x
0 + 7y = - 84
7y = - 84 ( divide both sides by 7 )
y = - 12
Substitute y = - 12 into either of the 2 equations and solve for x
Substituting into (1)
x - 2(- 12) = 32
x + 24 = 32 ( subtract 24 from both sides )
x = 8
solution is (8, - 12 )

Answer:
C
Step-by-step explanation:
4 X 4 X 4 X 4 X 4 and 4⁵
we can write 4 X 4 X 4 X 4 X 4 like 4⁵
4 X 4 X 4 X 4 X 4 = 4⁵
Answer:
Answer is TU = 15cm since n = 6 and n + 9 is 6 + 9 which is 15
I'm assuming it would be the same shape? That's also assuming that it's referring to congruent shapes and angles.
