Answer: Simplified form is $-4.2a+5.6b$

Step-by-step explanation:

Since we have given that

$(-2.4a-1.8b)-(-3.8a-4.4b)+(2.0a+3.0b)$

We first gather the like terms together:

$(-2.4a-1.8b)-(-3.8a-4.4b)+(2.0a+3.0b)\\\\=(-2.4a-1.8b)+3.8a+4.4b+2.0a+3.0b\\\\=-2.4a-3.8a+2.0a-1.8b+4.4b+3.0b\\\\=-4.2a+5.6b$

Hence, simplified form is $-4.2a+5.6b$

Answer:

Step-by-step explanation:

since we are looking for the hypotenuse we are to use SIN

sin 20.4=100/x

sin 20.4= 0.3486

so 0.3486x =100

divide both sides by 0.3486

so 100/0.3486

= 286.87m approximately

If f(x) = |2x - 4|, find f(-7)

Digiron [165]

hey there!!

Given :

f ( x ) = l 2x - 4 l , find f ( - 7 )

We will have to substitute the value of -7 instead of x

f ( -7 ) = l -14 - 4 l

f ( -7 ) = l -18 l

As the value in a mod shall always be positive, the answer would become 18

Hence, the required answer is 18

Hope my answer helps!!
