65x^2 + 212x - 133
you have to use the quadratic formula
x=( -b +/- √b²-4ac) / 2a
a is 65
b is 212
c is 133
because the first value is squared you will have 2 answers
x= 7/13
x= - 19/5
Answer:
8 in²
Step-by-step explanation:
The area of a triangle is always base times half height. Since this triangle has a 90° corner, the vertical 4 inch is also the height.
So area is 4*4/2 = 8

Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Mean distance of earth from the sun = 93 million miles
Let mean distance of earth from the sun = d
The variation on the distance is as much as 1. 6 million miles
Possible distances of the earth from the sun can be modeled using :
|d - 93| = ± 1.6
Where d = distance from earth to the sun
d = - 1.6 million + 93 million
d = 91.4 million
d = 1.6 million + 93 million
d = 94.6 million
Hence, possible distance from earth to the sun :
91.4 < d < 94.6
