Answer:
D
Step-by-step explanation:
Answer:
z = 4
y = -1
x = 2
Step-by-step explanation:
x - y = 3
Therefore => x = 3 + y
y + 2z =7
Therefore => y= 7 - 2z
We have the equation :
2x + 3y + 4z = 17
2(3 + y) + 3(7 - 2z) + 4z = 17
6 + 2y + 21 - 6z +4z = 17
2(7 -2z) - 2z + 27 = 17
14 - 4z - 2z + 27 = 17
-6z + 41 = 17
-6z = -24
z = 4
Answer:
46CM
Step-by-step explanation:
Perimeter = S + S + S + S + S + S + S +S
Perimeter = 9 + 7 + 8 + 5 + 5 + 8 + 2 + 2
Perimeter = 46 cm
The other 4 measurements:
5 is from the other side labelled 5 this is because they are equal.
8 is from the other side labelled 8 this is because they are equal too!
The twos are from the difference between 9 and 7.
