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.
I am joyous to assist you anytime.
4/6 is bigger
3/6 = 1/2 = 50%
4/6 = 2/3 = 66%
Answer:(all negative) 14 13 12 11 10
Step-by-step explanation: sall good
The given equation in the point slope form is expressed as
y + 3 = 1/2(x + 4)
The standard form for a point slope equation is expressed as
y - y1 = m(x - x1)
Where
m represents slope
By comparing both equations,
slope, m = 1/2
y1 = - 3(we know that y - - 3 = y + 3)
x1 = - 4(We know that x - - 4 = x + 4)
The slope intercept form is expressed as
y = mx + c
Where
c represents the y intercept
We would determine c by substituting x = - 4, y = - 3 and m = 1/2 into the slope intercept equation. It becomes
- 3 = 1/2 * - 4 + c
- 3 = - 2 + c
c = - 3 + 2
c = - 1
Substituting c = - 1 and m = 1/2 into the slope intercept equation, it becomes
y = x/2 - 1
The equation in slope intercept form is
y = x/2 - 1
