First calculate (-8x-15)=120
Then multiply - 11x120
=-1320
Lets say the width is W and the length is L,
So its W * L = 196
but we also know W*4 = L
which means we can substitute L for W * 4 so our equation will be
W*W*4 = 196
W*W = 49
W= 7
-3x > 0
Divide both sides by -3 remembering to "flip" the inequality as you do so, because it's negative.

Answer:
29
Step-by-step explanation:
Given the function f(x) = x/10x-3, if x = 0.30103;
substituting the value of x into the function;
f(0.30103) = 0.30103/10(0.30103) - 3
f(0.30103) = 0.30103/(3.0103 - 3)
f(0.30103) = 0.30103/0.0103
f(0.30103) = 29.226
f(0.30103) = 29 (to nearest whole number).
