1 answer:

3 0

*This is an answer I found elsewhere on Brainly.*

(4+√10)(4-√10)

=16-4√10+4√10-10

=6

------------------------------

(4+√10)+(4-√10)

=4+√10+4-√10

=8

----------------------------

The numbers are:

4+√10, and 4-√10

We can use a theorem called Proportional segments in right triangles.

1. How far is library from the park?
The perpendicular is the mean proportional between the segments of the hypotenuse, so:
 $PL= \sqrt{FL \cdot HL } = \sqrt{8 \cdot 2 } = \sqrt{16}=4 \ miles$

2. How far is the park from the football field?
Each leg of the given triangle is the mean proportional between the hypotenuse and the adjacent segment, so:
 $PF= \sqrt{FH \cdot FL } = \sqrt{(8+2) \cdot 8 } = \sqrt{80}=4 \sqrt{5} \ miles$

One leg of a right triangle is 7 inches longer than the other leg, and the hypotenuse is 35 inches. Find the lengths of the legs

lilavasa [31]

Answer: 21, 28

Step-by-step explanation:

Side #1 = x
Side #2 = x + 7
Hypotenuse = 35

Use the Pythagorean Theorem $a^{2}+b^{2}=c^{2}$ :

a = x
b = x + 7
c = 35

Substitute in the values & solve:

$x^{2}+(x+7)^{2}=35^{2}\\x^{2}+x^{2}+14x+49=1225\\2x^{2}+14x+49-1225=0\\2x^{2}+14x-1176=0\\2(x^{2}+7x-588)=0\\2(x + 28)(x - 21)=0\\x_{1}=-28, x_{2}=21$

-28 is not a possible solution since you can't have negative inches...

a = x = 21
b = x + 7 = 21 + 7 = 28
c = 35

How do you write 3 cubed

Varvara68 [4.7K]

3×3×3=27
3^3=27
3 Cubedis when you multiply 3 by 3 by 3, or in another words 3 by 3 times.
I hope this helped.

What is linear equation? What is quadratic equation?

mr_godi [17]

in the linear equation the greatest power of the variables is 1 for example:2X+4 this is a linear equation as the greatest power of the variable X is 1 also by drawing it in a graph you will obtain a straight line
while in the quadratic equation the greatest power is 2 for instance:X^2+4X-3 this is a Quadratic equation because the greatest power of the variable X is 2 also by drawing it on a graph you will obtain a parabola which is a curve "an upward curve or downward curve"
