Answer:
11.since diagonal are equal of rectangle
QS=RT
4x+6=6x-4
6+4=6x-4x
2x=10
x=10/2
x=5
now
diagonal :4x+6=4*5+6=<u>26</u>
12.
again
QS=RT
9x+12=11x-10
12+10=11x-9x
2x=22
x=11
now
diagonal=9*11+12=99+12=<u>111</u>
I believe it would be 13p im not for sure though
The total is 94 units.
A square has four equal sides so...
(5x-1)+(4x+3)+(5x-1)+(4x+3)=94
Combine like terms
19x+4=94
Subtract 4 from both sides
94-4=90
18x=90
Divide by 18 on both sides
90/18=5
X=5
Plug 5 in for x on the length of PQ
4(5)+3
20+3=23
Length of PQ=23 units
Answer:
Answer is given below, hope it helps
Step-by-step explanation:
22/4= 11/2
46/8= 23/4
58/10= 29/5
15
5x-2y=9......(1)
6x+ky=4......(2)
slope of eqn i= -5/-2
=5/2
slope of eqn ii = -6/k
since the line are perpendicular
5/2 * -6/k = -1
-30= -2k
k=15
