Hopefully this helps!
Answer:
x = -5
y = 20
Step-by-step explanation:
3x + y = 5
3x - 3x + y = 5 - 3x
y = 5 - 3x
--------------------------------------------------------
4x + 2y = 20
4x + 2(5 - 3x) = 20
4x + 2(5) + 2(-3x) = 20
4x + 10 - 6x = 20
10 - 2x = 20
10 - 10 - 2x = 20 - 10
-2x = 10
-2x ÷ -2 = 10 ÷ -2
x = -5
--------------------------------------------------------
y = 5 - 3x
y = 5 - 3(-5)
y = 5 + 15
y = 20
Answer:
3,-4 -2,-6 -5,3
Step-by-step explanation:
The formula of the surface area of any prism is,
Ph + 2B
P = 10 + 24 + 26 = 60
B = area
B triangle = ½ bh
B triangle = ½ 24 × 10 = 120
So,
60 × 34 + 2(120) = 2,280 cm²
