2 would be the base and 3 will be the square
Answer:
18
Step-by-step explanation:
To find this we must divide 45 by 20 which gives the answer of 2.25. As we know this we now must multiply that by 8 resulting in to 18.
Therefore the answer is 18
Answer:
Her son is 10 years old.
Step-by-step explanation:
Let son be x
Ellie is 4x
In 5 years time: Her son = x + 5
Ellie = 4x + 5
Given that she will then be 3 times as old as her son: 4x + 5 = 3(x + 5)
Solve x: 4x + 5 = 3(x + 5) ,4x + 5 = 3x + 15
x = 10
Answer:
g(1) = -6
Step-by-step explanation:
g(x) = -2x^2 - 4x
You want to solve for g(1). To do this make every x value in the original equation become 1.
g(1) = -2(1)^2 - 4(1)
Evaluate the exponent.
g(1) = -2(1) - 4(1)
Multiply.
g(1) = -2 - 4
Subtract.
g(1) = -6
Answer:
The answer is B. 70
Step-by-step explanation:
First, since K is the midpoint of line segment JL, JK must equal KL.
So, set 9x-1 = 2x+27 and solve.
7x=28 so x=4
Then, since they are asking for JL, using x=4, add together JK and KL.
So, 9x-1+2x+27 = 11x+26 = 11(4) + 26 = 44+26 = 70
