Well, First I would write it in the expanded form which is 16x^2-56x+49=44 then i would reorder my terms to 49+-56x+16^2=4 then solve for x so it would be 49+ -44 + -56 +16^2=44+ -44 then combine the like terms 49+ -44=5
5+-56x+16x^2= 44+-44 would turn into
44+ -44 =0
5+ -56+16^2=0
i would do the squaring and divide all the terms by 16 the coefficient of the squared term:
divide each side by 16 so
0.3125+ -3.5x+ x^2=0
move the constant to the right
add -0.3125 to each side 0.3125 + -3.5x + -0.3125 + x2 = 0 + -0.3125 then reorder
<span>0.3125 + -0.3125 + -3.5x + x2 = 0 + -0.3125
</span><span>0.3125 + -0.3125 + -3.5x + x2 = 0 + -0.3125
then
</span><span>x + -1.75 = 1.658312395
Simplifying
x + -1.75 = 1.658312395
Reorder the terms:
-1.75 + x = 1.658312395
Solving
-1.75 + x = 1.658312395
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '1.75' to each side of the equation.
-1.75 + 1.75 + x = 1.658312395 + 1.75
Combine like terms: -1.75 + 1.75 = 0.00
0.00 + x = 1.658312395 + 1.75
x = 1.658312395 + 1.75
Combine like terms: 1.658312395 + 1.75 = 3.408312395
x = 3.408312395
Simplifying
x = 3.408312395
then
</span>x + -1.75 = -1.658312395
Simplifying
x + -1.75 = -1.658312395
Reorder the terms:
-1.75 + x = -1.658312395
Solving
-1.75 + x = -1.658312395
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '1.75' to each side of the equation.
-1.75 + 1.75 + x = -1.658312395 + 1.75
Combine like terms: -1.75 + 1.75 = 0.00
0.00 + x = -1.658312395 + 1.75
x = -1.658312395 + 1.75
Combine like terms: -1.658312395 + 1.75 = 0.091687605
x = 0.091687605
Simplifying
x = 0.091687605
<span>
and finally your solution is x=3.408312395 and x=0.091687605
</span><span>
or another way to write it is
</span>x=\frac{1}{4}(7-2 \sqrt{11} )
[/tex]
x=\frac{1}{4}(7+2 \sqrt{11} ) [/tex]
Answer: the perimeter of the larger triangle is 22 units
Step-by-step explanation:
The diagram of both triangles is shown in the attached photo. The isosceles triangles are triangle ABC and triangle DEF
Perimeter of triangle ABC = 11
For an isosceles triangle, the other two sides are equal. If one equal side is x, then the sum of the two equal sides is x+x = 2x
Perimeter of triangle = sum of the lengths of the 3 sides. Therefore,
11 = 5 + 2x
2x = 11-5 = 6
x = 6/2 = 3
The base of the similar triangle is 10. It means that it is 2 times the base of the smaller triangle. That means the scale factor is 2. Therefore,
If the perimeter of the small triangle is 11, the Perimeter of the larger triangle will be 2 × perimeter of the smaller triangle. This becomes
2 × 11 = 22 units.
It can also be determined by adding the length of each side
3×2 + 3×2 + 5×2 = 6+6+10 = 22 units
