Answer:
−15x2+23x−6
Step-by-step explanation:
(3x−1)(−5x+6)
=(3x+−1)(−5x+6)
=(3x)(−5x)+(3x)(6)+(−1)(−5x)+(−1)(6)
=−15x2+18x+5x−6
=−15x2+23x−6
Answer:
(-A)^2 for A = 5
(-5)^2

Step-by-step explanation:
3y +4 =5y -10
2y = 14
y = 7
DEF = (3Y+4)× 2 OR (5Y-10) ×2 OR (5Y-10+ 3Y+4)
Def= (3 ×7+4)×2
=50 degree
Answer:
