Answer:
Yes
Step-by-step explanation:
Yes , if both pairs of opposite sides of a quadrilateral are congruent then the quadrilateral is a parallelogram . The parallelogram has opposite sides equal and parallel . Diagonals bisect each other . The sum of alternate angles is 180° and the opposite angles are equal .
Simply plug in the value for x.
If x is equal to -18, then plug in -18 for x.
Example:
f(x) = 15 + x/5.
f(5) = 15 + 5/5.
Then solve the equation.
A function is just something that receives some value and then barfs a value out. This is an IO relationship. (Input/Output).
Step-by-step explanation:
x²+2x+1
x²+x+x+1
x(x+1)1(x+1).
(x+1)(x+1)
x=-1. , x=-1

Answer:
Step-by-step explanation:
let the no of girls be x
ratio of boys to girls=4:7
4/7=16/x
do cross multiplication
7*16=x*4
112=4x
112/4=x
28=x
therefore there are 28 no of girls.
