-1 > -2(x-4) - 5(4x - 7)
-1 > -2x + 8 - 20x + 35
-1 > -22x + 43
-1 - 43 > - 22x
-44 > - 22x
-44/-22 < x
2 < x....or x > 2
Answer:
a) 5
b) 20
c) 28
d) 10
Step-by-step explanation:
a) 7-2=5
b) 2(7)+3(2)
= 14+6
= 20
c) 2(7)(3)= 28
d) (7-2)^2
= (14-4)
= 10
We know that
in a right triangle
Applying the Pythagoras Theorem
c²=a²+b²
in this problem
c=√87 yd
a=√23 yd
b=?
so
b²=c²-a²-----> b²=(√87)²-(√23)²----> b²=87-23----> b²=64----> b=8 yd
the answer is
8 yd
