Absolute value simply removes the sign from a number making both negative and positive numbers positive. That means that the absolute value of both a positive and a negative number have the same value.
That means |-7| = 7 and |7| = 7
So |-2| = 2 and |2| = 2
|1/3| = 1/3 and |-1/3| = 1/3
Answer:
Step-by-step explanation:
5) -7 (-15w + 21) + 3(18 - 27w)
Step 2: 105w - 81w - 147 + 54
6)
step 3: 24w - 93
Answer:
Option (6)
Step-by-step explanation:
Name f the planes of the figure given,
Plane JKL or plane Z
Plane PSR
Plane PQK
Plane SRL
Plane PSM
Plane QRL
Therefore, the number of planes of the box standing vertical on a table are 6.
Option (6) will be the answer.
Answer:
a) x (x-9) (x+3)
b) x (x+4)(x-4)
c) (x)(x)(x + 16)
Step-by-step explanation:
We're going to equal the functions to zero and find their roots by factorizing:
a) f(x)=x³-6x²-27x
x³-6x²-27x = 0
x(x²-6x-27) = 0
⇒x (x-9) (x+3)
b) f(x)=x³-16x
x³-16x = 0
x (x²-16) =0
⇒x (x+4)(x-4)
c) f(x)=x³+16x²
x³ + 16x² = 0
x² ( x +16)
⇒(x)(x)(x + 16)
