Answer:
= 
−7x−20
Step-by-step explanation:
(2x−5)(3x+4)
= (2x+−5)(3x+4)
= (2x)(3x)+(2x)(4)+(−5)(3x)+(−5)(4)
= +8x−15x−20
= −7x−20
Answer:
112, 119 and 126.
Step-by-step explanation:
Let the consecutive multiples of 7 be 7n, 7(n+1) and 7(n+2) where n is an integer, then:-
7n + 7n + 7 + 7n + 14 = 357
21n + 21 = 357
21(n + 1) = 357
n = (357/21) - 1
n = 17 + 1 = 16.
So the numbers are 7*16 = 112, 7*17 = 119 and 7*18 = 126.
SinA=cos(90-A)
Notice here 52=90-38
so the answer is 0
