You need to use FOIL
(3d+5)+(d-2)=3d^2-6d+5d-10=3d^2-1d-10
Answer:
i actually dont know im so sorry but i will keep trying to find the answer
Answer:
assuming you're asking whats g(2+3) the answer is 40
Step-by-step explanation:
8(2+3)
8(5)
8 x 5 = 40
:))
A square's diagonal has a length equal to √(2) times the length of its sides. So if the side length is <em>x</em>, then the diagonal is such that
√(2) <em>x</em> = 10 cm
→ <em>x</em> = 10/√(2) cm ≈ 7.07 cm
The perimeter of a square is 4 times its side length, so the perimeter is
4 (10/√(2) cm) = 40/√(2) cm ≈ 28.3 cm
which makes 28.4 cm the closest answer.
