Ok, so if he walks 4 miles per 64 minutes, or 4 miles/64 min which will
reduce to 1 mile/ 16 min, then the numbers of miles he walks in a given
number of minutes would be
1/16 * number of minutes
The question states we represent miles with y and number of minutes with x, so...
y = 1/16x
So let's check it...
How many miles (y) in 64 minutes (x)
y = 1/16x
y = 1/16 * 64
y = 64/16 = 4 miles
Yep! It checks!
Answer:
A = 177.46
Step-by-step explanation:
![A = lw + l\sqrt{(\frac{w}{2})^{2} + h^{2}} + w \sqrt{(\frac{l}{2})^{2} + h^{2}](https://tex.z-dn.net/?f=A%20%3D%20lw%20%2B%20l%5Csqrt%7B%28%5Cfrac%7Bw%7D%7B2%7D%29%5E%7B2%7D%20%2B%20h%5E%7B2%7D%7D%20%2B%20w%20%5Csqrt%7B%28%5Cfrac%7Bl%7D%7B2%7D%29%5E%7B2%7D%20%2B%20h%5E%7B2%7D)
A = 6*6+6root((6/2)^2+11.4^2)+6root((6/2)^2+11.4^2)
A = 177.46
Answer:
Step-by-step explanation:
hello :
5x²+8x-4 quadratic expression when : a = 5 and b=8 and c= -4
∆ = b²-4ac ∆ = 8²-4(5)(-4) = 64 +80 = 144 = 12²
X1 = ( -b -√∆)/2a X1 = (-8-12)/10 = -20/10= -2
X2 =(-b+√∆)/2a X2 = (-8+12)/10 = 4/10 = 2/5
us factorisation : a(X-X1)(X-X2)
5x²+8x-4= 5(x+2)(x-2/5) = (x+2)(5x-2)
you can verify ; (x+2)(5x-2) = 5x²-2x+10x-4 = 5x²+8x-4
