<span>Let the extension of the length and width be x.
The new dimensions are: Length = 8+x
Width =3+x
Area = 104 ft squared
Area of a rectangle = Length x Width
Therefore,
(8+x)(3+x) = 104
x^2 +11x +24=104
x^2 +11x +24-104=0
x^2 +11x-80=0
Factorize using splitting the middle term method.
X^2 +16x-5x-80=0
x(x+16)-5(x+16)=0
(x-5)(x+16)=0
either x-5 = 0 or x+16=0
x=5 or x=-16
length and width measure cannot be negative.
Therefore, the extension of the length and width is 5 feet each.</span>
Answer:
The degrees of freedom for the chi square statistic is 7-4=3
If 21 Ib on moon=126 IB on earth
25 Ib on moon=?
25/21*126=150
Therefore the astronaut will weigh 150Ib on earth
Answer:
u=72
v=61
Step-by-step explanation:
for U:
54+54=108
180-108=72
For V:
180-58=122
122/2=61
A. -4
b. -6
c. 0 if the expression is 6 - 8 + 2 but if it is 6 - 8 ÷ 2 = 2
d. -2.1
