Answer:
x^2 + x -12
Step-by-step explanation:
I am going to expand and simplify because you haven't mentioned what to do:
(x-3)(x+4)
x^2 +4x -3x- 12
x^2 +x-12
Answer:
Morse electronics sells 5 computers
Micro knowledge sells 25 computers
Step-by-step explanation:
The computation is shown below:
Let us assume the morse electronics computer be x
So the micro knowledge computers be 5x
And, the difference between them is 20
Now the equation is
5 x - x = 20
4x = 20
x = 5
Hence, the morse electronics sells 5 computers
While on the other hand the micro knowledge sells
= 5 × 5
= 25 computers
Answer:
Step-by-step explanation:
(x-3)/2 = 9
x - 3 = 18
x = 21
(y-5)/2= 6
y - 5 = 12
y = 17
(21, 17)
Answer: 336 cm²
Step-by-step explanation:
A trapezoid looks like a rectangle with 2 traingles attached to the side, yeah? So imagine cutting off those 2 triangles. In the middle you have a rectangle with the dimensions of 14 cm by 16 cm. The area of that rectagle is 224 cm². By subtracting the top base length from the bottom base length, you get the length of the two triangles. So, it would be 28 cm - 14 cm, giving you 14 cm. There were 2 triangles, so cut that length in half and you get 7 cm for the base of one traingle. To find the area of 1 traingle, you would do 1/2 multiplied by 7 multiplied by 16. But you have 2 triangles. so the 1/2 step isn't needed because if you put the two triangles together, you get a new rectangle. Thus, when you add the area of this new rectangle, you get 112 cm². Add this to the original rectangle, and your final area is 336 cm².
