4 toys * 4 months = 16
16 toys + 3 toys he started with =19
19 toys
5x(x+4)
Step by step
5x^2 = 5x(x) because it’s the largest you can divide by
20x =4 because 5x times by 4 = 20x
Which means 5x^2+20x = 5x^2+20x= 5x(x+4)
Numbers my dude good luck
Answer:
Step-by-step explanation:
Start by drawing five rectangles. Divide each of the five into four parts. You should have 20 sections. 1 1/4 is equal to 5/4, or five 1/4 pieces. Shade or erase five of the 20 sections. There should be 15 left. 15/4 is 3.75, or 3 3/4, which is less than four.
Hope this helps!
The first equation tells you that
. If you substitute this expression for
in the second, we have
![2x-(x+3)=-1 \iff x-3=-1 \iff x=2](https://tex.z-dn.net/?f=2x-%28x%2B3%29%3D-1%20%5Ciff%20x-3%3D-1%20%5Ciff%20x%3D2)
And we can deduce ![y=x+3=2+3=5](https://tex.z-dn.net/?f=y%3Dx%2B3%3D2%2B3%3D5)
