I don’t see any multiple choice but d3 -343 is factored as (d-7)(d^2+7d+49)
Answer:
x= -6
y= -5
Step-by-step explanation:
(x,y) = (-6, -5)
No it is not correct the answer is 14!
Answer:
Hello! answer: 39
Step-by-step explanation:
Formula for triangles area: base × height ÷ 2
Formula for squares area: base × height
5 × 3 = 15 15 ÷ 2 = 7.5 since there are 4 triangles that are the exact same I will just multiply by 4 so I have all the triangles so 7.5 × 4 = 30 now the square is just 3 × 3 so... 3× 3 = 9 now we add these up 30 + 9 = 39 therefore the surface area is 39
