Answer:
C
Step-by-step explanation:
y = (x-1) (x+4)
when y=0
x=1 and x= -4
so select C
First add 45 and 55 because sum means addition. 45+55=100 and teiple means multiplication and 3x100= 300 hope this helped :)
Hi there!
Answer:
1/6
Explanation:
The first probability of getting blue is 4 out of the total marbles so 4/9.
The second time there are only 3 blue marbles out of 8 now so 3/8.
So the answer is 4/9X3/8
which equals 12/72 or 1/6
Hope this helps!
I`m not sure of the answer but if you look up Math Way it might be able to help.
Hi there!

We can use the Pythagorean Theorem to solve:
Use the formula a² + b² = c² where:
"a" and "b" are the legs
"c" = Hypotenuse
The diagonal side, or the length of the ladder is 10cm, and one of the legs of the triangle is 8cm, therefore:
(8)² + b² = 10²
64 + b² = 100
Subtract 64 from both sides:
b² = 36
Take the square root of both sides:
√b² = √36
b = 6 cm. This is the distance of the wall from the foot of the letter.
