Step-by-step explanation:
parallelogram area is:h×base
10×14=140
we have two so
140×2=280
traingle is:h×base/2
18-10=8=h
8×14/2=56
56×3=168
168+280=448
Answer:
She factored out a 4 from the equation.
Step-by-step explanation:
So our original equation is 12x + 4 = 20x - 12
Anika's first steep of her equation is 3x + 1 = 5x - 3
We know that the terms were not moved around, so the first step was likely multiplication or division.
We also see that a 4 has been factored out of the entire equation, like this:
12x + 4 = 20x - 12
4(3x + 4) = 4(5x - 3)
And these 4's cancel each other out.
So, I conclude that Anika's first step was dividing the entire equation by 4 or factoring out a 4 from the equation.
5/2(6w - 16) = 18w - (3w + 40)
15w - 40 = 15w - 40
this equation is true.
Answer:
The first term of the series is 125.
Step-by-step explanation:
The sum of the first four terms of a geometric series can be described by the following equation:
Where x1 is the first term and r is the common ratio. Replacing the given values into the equation to solve for x1 yields:
The first term of the series is 125.
Answer: y = 9x/7 − 6/7
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
