Answer:
15 ft
Step-by-step explanation:
Hi, the illustration for the problem is a right triangle with:
hypotenuse (C)= the length of the ladder = L
horizontal side(A) = distance from bottom of the ladder to the building = L - 6
vertical side(B) = distance from the top of the ladder to the bottom of the building = L - 3
So, we can use Pythagoras formula:
A2 +B2= C2
(L – 6 )² + (L-3)² = L²
L²-12L+36+L²-6L+9 =L²
L2 -18L+45 =0
APPLYING QUADRATIC FORMULA WE OBTAIN:
L =15 OR L=3
If L=3
Vertical side = L-3 = 0 (Length can´t be 0)
So L=15
It is an irrational number. A number is rational if it can be expressed as a quotient of 2 integer numbers. Number π2 cannot be expressed as a quotient of integers, so it is an irrational number.
Answer:

Step-by-step explanation:
I hope the following will help you understand what this diagram means:-
The 4 people in the area overlapped by the Music and Spanish areas are the people who are in both clubs.
Obaid and Abdulraheem are in the Music Club only.
The number of members in the Music Club is these 2 plus the 4 in the overlap area, so there are 6 members in the Music Club.
Answer:
A
Step-by-step explanation:
The slope is positive. Also, using the rise/run method, I found that the slope is 3. The b is 4 because the line crosses the y axis at 4.
Answer:
−4x + 10 < 26
Step 1: Subtract 10 from both sides.
−4x + 10 − 10 < 26 − 10
−4x < 16
Step 2: Divide both sides by -4.
-4x/−4 < 16
/−4
x > −4
Answer:
x > −4
