Answer: Second Option is correct.

Step-by-step explanation:

Since we have given that

x^2+5x-6=0

We need to calculate the solutions to the equation :

We will use "Split the middle terms" :

x^2+5x-6=0\\\\x^2+6x-1x-6=0\\\\x(x+6)-1(x+6)=0\\\\(x+6)(x-1)=0\\\\x+6=0;x-1=0\\\\x=-6,1

So, Second Option is correct.

The quadratic equation is;
x²+5x-6 = 0
x²+6x-x-6 = 0
x(x+6)-1(x+6) = 0
(x+6)(x-1) = 0
So,
x+6 = 0 and x-1 = 0
x=-6 and x = 1
Thus the answer is
x = -6,1

horrorfan [7]
So 20=80%' % means out of 100 so 80%=80/100 so 20=80/100 we try to get to 100/100 so 20=80/100 5=20/100 5 times 20=100 so 25=100/100 there were 25 questions total

Which is steeper, a slide that rises 3 feet for every 2 feet of run, or a sliding pole that rises 5 feet for every 3 feet of run
mezya [45]

Answer:

59.03° is greater than 56.31°' This means that the sliding pole that rises 5 feet for every 3 feet of run making an angle of inclination of 59.03° is steeper than the angle of inclination made by a sliding pole that rises 3 feet for every 2 feet run.

Step-by-step explanation:

Step 1

Express the angle of inclination as follows;

Tan∅=H/R

where;

∅=angle of inclination

H=vertical rise

R=distance of run

Step 2

Determine the angle inclination when;

H=3 feet

R=2 feet

replacing;

Tan∅=(3/2)=1.5

∅=Tan^(-1)(1.5)

∅=56.31°

Determine the angle inclination when;

H=5 feet

R=3 feet

replacing;

Tan∅=(5/3)=1.67

∅=Tan^(-1)(1.67)

∅=59.03°

59.03° is greater than 56.31°' This means that the sliding pole that rises 5 feet for every 3 feet of run making an angle of inclination of 59.03° is steeper than the angle of inclination made by a sliding pole that rises 3 feet for every 2 feet run.
