X^2-8x-7=0
Add 7 to both sides
X^2-8x=7
Now use formula
(B/2a)^2
(-8/2)^2= 16
Add 16 to left subtract from right to get
X^2-8x+16=-9
Now factor into
(X-4)^2=-9
For your final answer

Which equation can be used to calculate the surface area of the triangular prism net show below?
slava [35]

The equation  that can be used to calculate the surface area of the triangular prism net shown below is mathematically given as

SA = (1/2)(5)(12) + (1/2)(5)(12) + (5)(2) + (12)(2) + (13)(2)  

<h3>Which equation can be used to calculate the surface area of the triangular prism net shown?</h3>

Generally, The region or area that is occupied by the surface of any particular item is referred to as that object's surface area.

In conclusion, the equation surface area of the triangular prism will be one that accommodates all parameters

SA = (1/2)(5)(12) + (1/2)(5)(12) + (5)(2) + (12)(2) + (13)(2)  

SA = (1/2)(5)(12) + (1/2)(5)(12) + (5)(2) + (12)(2) + (13)(2)

Help Me Now! What is the rate of change for Funtions 1 and 2.​
lutik1710 [3]

Function 1 Answer: 45

Function 1 Explanation: The rate of change (ROC) is basically the same thing as the slope of a graphed function. If you were to graph this table onto a coordinate plane, the slope of the line formed would be 45. (see Function 2 Explanation for more explanations, duh.)

Function 2 Answer: 40

Function 2 Explanation: Functions can be written in slope-intercept form, like this: y = mx + b. The <em>m</em> is the slope, or ROC (above), and the <em>b</em> is called the y-intercept, or where the line crosses the y-axis. The m in that equation is 40...

Hope that helps!! Sorry that took so long...

What is the simplified form of the following expression? 3 sqrt 4x/5
SVEN [57.7K]

Answer:

6 \sqrt{ \frac{5x}{5} }

Explanation:

Simplify the radical by breaking the radicand up into a product of known factors, according to the Rational-Radical Rule:

\sqrt[n]{\frac{a}{b}} =  \frac{ \sqrt[n]{a}}{ \sqrt[n]{b} }

In the end, you bring √5 to the numerator, giving you 5x, leaving 5 in the denominator.

I hope this helps you out alot, and as always, I am joyous to assist anyone at any time.
