The GCF Of All Those Numbers Would Be 7.
6(7)= 42
12(7)= 84
15(7)= 105
Answer:
1. It should be 7
2. They have $46
Step-by-step explanation:
1. You make a system of linear equations from this. So it would be y= 5x+11 where x is the number of weeks and y is the money. And the second linear equation is y=-2x+60. Then you substitute it. You make it 5x+11=-2x+60. Then you solve it normally and you got your answer but remember in this case they are asking for the x. So make sure to submit the x and not the y.
2. For this it is the same thing except they are asking for the y not the x.
X= width
length= 3x-7
Area: (x)(3x-7)=40
= 3x^2-7x=40
= 3x^2-7x-40=0
Factorise the equation: (3x+8)(x-5)=0
x=-8/3 (reject because width cannot be negative) or x=5
so width is 5cm and length is 3(5)-7= 8cm !
The answer is yes ok can I be brainliest?
Answer:
A pure imaginary number can be written in bi form where b is a non-zero real number and i is the imaginary i. ... When this occurs, the equation has no roots (zeros) in the set of real numbers. The roots belong to the set of complex numbers, and will be called "complex roots" (or "imaginary roots").
