1 answer:
Simora [160]4 years ago
5 0

Answer:

Step-by-step explanation:

128 - 6x - 39 + 5x = -31 + 9x

89 -x = -31 + 9x

10x = 120

x = 12

m<QRS= -31 + 9(12)= -31 + 108= 77

m<TRS= -39 + 5(12)= -39 + 60= 21

m<QRT= 128 - 6(12)= 128 - 72 = 56

Find the HCF and LCM of 4x^2 - 36 ,2x^2 - 12x + 18 and 2x^2 + x - 21​
olga_2 [115]

Answer:

(x-3), 4 (x - 3)^2 (x + 3) (2 x + 7)

Step-by-step explanation:

Factor all the expressions,

1st expression= 4x^2 - 36=4(x^2-9)=4(x+3)(x-3)

2nd expression=2x^2 - 12x + 18 =2(x^2-6x+9)=2 (x - 3)^2=2(x-3)(x-3)

3rd expression=2x^2 + x - 21​=(x - 3) (2 x + 7)

HCF=Commo factor=(x-3)

LCF=Common factor*Remaining factor=4(x+3)(x-3)(x-3) (2 x + 7)=4 (x - 3)^2 (x + 3) (2 x + 7)
