Answer:
Step-by-step explanation:
<u>Find zeros first:</u>
x² + x - 6 = x² + 3x - 2x - 6 = x(x + 3) - 2(x + 3) = (x - 2)(x + 3) x = 2, x = -3, x = 7 (but x ≠ 7 as no division by zero) <u>We have 4 intervals:</u>
x ≤ - 3, three negatives, the result is negative or zero -3 ≤ x ≤ 2, two negatives and one positive, the result is positive or zero 2 ≤ x < 7, two positives and one negative, the result is negative or zero x > 7, three positives, the result is positive or zero <u>The solution is:</u>

Step-by-step explanation:
Distribute 2z-1=z+8-2z add like terms 2z-1=-z+8 add z to both sides 3z-1=8 add 1 to both sides 3z=9 divide both sides by 3 z=3
Answer: B
Step-by-step explanation: divide 75 by 25 to find how many feet you travel in 1 second (75/25=3) then you take 3 times 10 to see how many feet you travel in 10 seconds (3x10=30).
Length=x Breadth=1/3x (x+1/3x)×2=80 4/3x×2=80 8/3x=80 x=30 Length=30 Breadth=1/3×30=10 Hope my answer helped u :)
