Answer:
The solve of this equation is X = 4,06
Step-by-step explanation:
To solve this formula:
2 ( X² - 16) = 1
You must use the distributive law of multiplication, thus:
2X² - (16×2) = 1
2X² - 32 = 1
2X² = 1 + 32
X² = 33/2
X² = 16,5
X = √16,5
X ≈ 4,06
Thus, the solution of this equation is:
<em>X ≈ 4,06</em>

Answer:
12 its right
Step-by-step explanation:
It's scientific notation, so 1.4x10^7 would be 14000000 <span />
Answer:
782
Step-by-step explanation:
You have to multiplied 23 and 34
23 X 34 = 782
41.2 cm
Step-by-step explanation:
subtract the y's and x's to get the distances
left & right sides are hypotenuses
top :
10 - (-2) = 12
bottom :
5 - (-7) = 12
left :
3 - (-4) = 7 = height
-7 -(-2) = -5 = 5 = base
pythagorean theorem
49 + 25 = 74
square root of 74 = 8.6
right :
same
perimeter :
12 + 12 + 8.6 + 8.6 = 41.2
