Answer:
16 = l
4 = w
Step-by-step explanation:
{64 = wl
{40 = 2w + 2l
{l = 8 + 2w
64 = w[8 + 2w] ↷
-64 + 8w + 2w² ↷
[2w² - 8w] + [16w - 64]
2w[w - 4] 16[w - 4]
[w - 4][2w + 16] = 0

This is the expression we want because when we talk about dimensions, we want NON-NEGATIVE numbers. The other expression results in -8 = w, and we do not want that; this expression gives us a solution of 4 = w, and THIS is exactly what we want. Anyway, you plug "4" back into the system of equations and you will get a length of 16 centimetres.

376 tulips and 423 Dahlias.
cause 8 times 47 is 376
And 9 times 47 is 423
And those answers together and you get 799
1. Distribute the Negative Signs
2. Combine like terms
-2x^2 + 12x-7
27/12=2.25
So ur answer is 2.25m
hope it helped and dont forget to mark as the branliest :)
