Question

Can someone plz help me with this?

Answer 1

10.

5x+23=8x-19

23+19=8x-5x

3x=42

x=42/3

x=14

11.

14x-13=8x+5

14x-8x=13+5

6x=18

x=18/6

x=3

.12.

4x+7=10x-41

10x-4x=41+7

6x=48

x=48/6

x=8

so

h=10×8-41=39

b=17

p=SV

By using Pythagoras law

p²+b²=h²

SV²=39²-17²

SV²=1232

SV=√1232

SV=35.09=35
