Answer: 1:3
Step-by-step explanation: for 4 toads you have 12 frogs so the ratio is 4 to 12. But you can simplif, divide each side by 4 so it’s 1 to 3
Answer:
16
Step-by-step explanation:
Given
x² + 8x = 4
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(4)x + 16 = 4 + 16, thus
(x + 4)² = 20 ← equivalent equation
Answer:
Below
Step-by-step explanation:
First, find the difference. You would do
-19 - (-9) = -10
-9 - 1 = -10 and so on...
The difference is -10
Now you need to find what number will make 11 when added to -10.
11 - (-10) = 21
The equation:
y = -10x + 21
Answer:
x = 2 and x = -3
Step-by-step explanation:
We need to find the value of x in the below expression.
Adding 1 to both sides,
Squaring both sides,
Hence, this is the required solution.
