If you would like to find 2 numbers which you can add up to get 24 and multiply to get -25, you can calculate this using the following steps:
a + b = 24 ... b = 24 - a
a * b = -25 ... a * (24 - a) = -25 ... 24 * a - a^2 = -25 ... 0 = a^2 - 24 * a - 25
0 = (a - 25) * (a + 1)
1. a = 25
2. a = -1
b = 24 - a
1. b = 24 - 25 = -1
2. b = 24 - (-1) = 25
The numbers you are looking for are -1 and 25.
Answer:
6 cm
Step-by-step explanation:
Given the information :
V=720 cm
L=?
P=15 cm
T=8 cm
The volume = L * P * T
V = L * P * T
720 = L * 15 * 8
720 = L * 120
L = 720 / 120
L = 6 cm
Answer:
Percentage of votes in favour of new speed limit=50%
Step-by-step explanation:
There was a voting in Molly's town to set a new limit for the speed attained by a vehicle.

For that,the percentage of votes in favour=
Percentage of votes in favour=
Percentage of votes in favour=50%
Answer:
D
Step-by-step explanation:
The expression is 
We can follow the rule of "PEMDAS" here.
PEMDAS = Parenthesis, Exponents, Multiply, Divide, Add, Subtract
So, we first need to deal with Parenthesis. Next,
There aren't any exponents, so we deal with Multiplication of 7 and 3.
Then addition/subtraction.
Hence, the first step, from the answer choices, would be D, multiply 7 and 3
