Step-by-step explanation:
the answer as shown in the photo
See it is < and not ≤ so we don't include -4
put a circle around -4 but don't shade it in
to get there, move 4 units left from 0
then we see x is less than -4
so shade to the left of the circle
Answer: X>7
Step-by-step explanation:
5x>35
Divide both by 5
5x/5=x
35/5=7
Answer:
18
Step-by-step explanation:
subtract 3 from both sides
then divide by -2/3 from both sides and flip the inequality sign
then you get h > 36/2
Then h > 18
The situation forms the right triangle above:
Where x is the length of the ladder.
Apply the Pythagorean theorem:
c^2 = a^2 +b^1
where:
c = hypotenuse = longest side = x
A &b = the other 2 legs of the triangle
Replacing:
x^2 = 60^2 + 15^2
Solve for x
x^2 = 3,600 + 225
x^2 = 3,825
x =√3,825
x = 61.85 ft
