= (x +7)(x - 3)
hope that helps

Answer:
1 dollar is equal to 0.75 E
Step-by-step explanation:
120$ = 90 e -----> 4$ = 3E
250$ = 187.50 e -----> 4$ = 3E
400$ = 300 e -----> 4$ = 3E
----------------------------------
from this we know 4$ = 3E
1 E = 4$/3
1 E = 1.33...$
---------------------
1 $ = 3/4 E
1 $ = 0.75 E
---------------------
1.33...$ dollars is equal to 1 E and
1 $ is equal to 0.75 E
-----------------------------------
90 x 1.33... =120
187.50x1.33...= 250
300 x 1.33... = 400
--------------------------
There’s a pattern to this and I’ll explain in the comments if you want to know or can’t figure it out :)
1.) 27/x^3
2.) a^8/b^12
3.) 7^36/81 OR 13,841,287,201/81
4.) 256m^20/n^4
5.) x^6y^6
6.) 64k^4/k^6
7.) 1,000a^9b^6/a^6b^9
8.) 81x^21/625
9.) 2304/x^16y^12
10.) x^7z^14/y^21
11.) 7,776k^5
12.) x^24y^24/4,096
Hope it’s all helped
