How do you determine if the line segments are congruent

Gemiola [76]

You must calculate the length of the segments.

Suppose segments AB and CD
Being A (m, n), B (p, q) C(r,s) and D(t,u)
<span>
They are congruent if:

</span> $\boxed{(p-m)^2+(q-n)^2=(t-r)^2+(u-s)^2}$ <span>

</span>

Can someone simplify pls

algol [13]

we are given to simplify

$\\ \ (x^6y^5)(5xy^2)(-6x^4)\\ \\$

Open the bracket and write the like terms together

$\\ \ =x^6y^5*5xy^2*(-6)x^4\\ \\ \ =-30x^6*x*x^4*y^5*y^2\\ \\$

when the bases are same then the exponents gets added

$\\ \ =-30x^{6+1+4}y^{2+5}\\ \\ \ =-30x^{11}y^7$
