If you take a lokk at the picture I used an online algebra calculator to check my answer against to gurantee the corectness of my answer for you.
Answer:
X = 48
Step-by-step explanation:
<em>to </em><em>find </em><em>X </em><em>we </em><em>must </em><em>first </em><em>make </em><em>it </em><em>the </em><em>subject </em><em>of</em><em> </em><em>the </em><em>formula</em><em>,</em><em> </em><em>so</em><em>,</em><em> </em><em>X </em><em>=</em><em> </em><em>1</em><em>6</em><em> </em><em>×</em><em> </em><em>3</em><em> </em><em>=</em><em> </em><em>4</em><em>8</em>
<em>X </em><em>=</em><em> </em><em>4</em><em>8</em><em>.</em>

Answer:
The discrimant of this equation is 144.
Step-by-step explanation:
First you have to move all the variables to one side to make the equation/expression into 0 by substracting 8x² to both sides :
9x² + 14x + 13 = 8x²
9x² + 14x + 13 - 8x² = 8x² - 8x²
x² + 14x + 13 = 0
It is given that the formula of discriminant is, D = b² - 4ac where a&b&c represent the number of the equation, ax²+bx+c = 0 :
x² + 14x + 13 = 0
D = b² - 4ac
= 14² - 4(1)(13)
= 196 - 52
= 144
Step One
Find the area of the base
A = s * s
s = 755.5 feet
Area = 755.5^2
Area = 570780.25 square feet.
Step two
Multiply the volume by 3
V = 1/3 B * h
3*V = B * h
V = 85600000
85600000 * 3 = B * h
256800000 = B * h
Step Three
Divide by B
B = 570780.25
256800000 = 570780.25 * h
256800000 / 570780.25 = h
449.91 feet = h
Answer:
C) 12
Step-by-step explanation:
Absolute value always means it is the positive version of the number
This switches -7 to 7 and 5 stays the same.
5 + 7 = 12
