Answer:
shortest side = 3 in
Step-by-step explanation:
Sum the 3 sides and equate to 13, that is
x - 5 + 6 +
= 13, that is
x + 1 +
= 13 ( subtract 1 from both sides )
x +
= 12 ( multiply through by 2 to clear the fraction )
2x + x = 24
3x = 24 ( divide both sides by 3 )
x = 8
Thus
x - 5 = 8 - 5 = 3 and
=
= 4 , then
The shortest side is x - 5 = 3 in
Answer:
6
Step-by-step explanation:
Answer:
A. x = -2, x = 1.25
Step-by-step explanation:
<u>Use the </u><u>quadratic</u><u> formula</u>
x = 
Once in standard form, <u>identify</u> a, b, and c from the <u>original</u> equation and plug them into the <u>quadratic formula</u>.
4x² + 3x - 10 = 0
a = 4
b = 3
c = - 10
x = 
<u>Simplify</u>
<u>Evaluate the exponent</u>
x = 
<u>Multiply</u> the numbers
x = 
Add the <u>numbers</u>
x = 
Evaluate the <u>square root</u>
x = 
<u>Multiply</u> the numbers
x = 
<u>Separate</u><u> the equations</u>
To solve for the <u>unknown variable</u>, separate into two equations: one with a plus and the other with a minus.
x = 
x = 
<u>Solve</u>
Rearrange and isolate the <u>variable</u> to find each <u>solution</u>
x = - 2
x = 1.25
The product of 12 and x.
