only two. That is absolute value, so -3=x would be transfo into 3 by the absol values. And ofc 3=3.
so two numbers would fit as the x variable 3 and -3
9/10-2/5= first you must get a common denominator
you don't have to change the first fraction but the second one 2/5 multiply the top and bottom number by 2
9/10- 4/10=5/10 is the answer but you can simplify because 5 divides into 10 so 5 goes into 5 1 time and 5 goes into 10 2 times
final answer is 1/2
34x - 136 = 9
(34x - 136) + 136 = 9 + 13634x = 14534x / 34 = 145 / 34x = 4.26470588235x = 4.26 (2 dp.)
Answer:
V = 15.75w² + 10.5w
Step-by-step explanation:
A rectangular prism is the same as a cuboid and the volume of a cuboid is length multiplied by width multiplied by the height.
And we were provided with the following:
Length = 5.25cm
Width is unknown,= w
The height is said to be 2cm longer than 3 times it's width.
The above statement can be mathematically represented as ;
H = 3w + 2
Apply the above into the formula given and we have
5.25 × w × (3w + 2)
Expand the above and we have
V = 5.25w × (3w + 2)
V = 15.75w² + 10.5w
