Answer: 36
Step-by-step explanation:
(11−9)^2(8−5)^2
=(22)((8−5)^2)
=4(8−5)^2
=4(3^2)
=(4)(9)
=36
Answer:
Step-by-step explanation:
Hey i think ur answer is C
Answer:
11.45mm^2
Step-by-step explanation:
Given data
Circumference= 12mm
The expression for the circumference is
C= 2πr
12= 2*3.14*r
12= 6.28r
r= 12/6.28
r= 1.91mm
Hence the area of each small circle is
A= πr^2
A= 3.14*1.91^2
A= 3.14*3.6481
A=11.45mm^2
Answer:
x = 1, -5.56
Step-by-step explanation:
x^2 = -7x - 8
shift -7x and -8 to the other side . Remember when u shift minus changes into plus.
x^2 + 7x + 8 = 0
using quadratic equation formula
in quadratic equation one value comes positive and other comes in negative
a = 1 , b = 7 and c = 8
taking positive sign
x = (-b +
) /2*a
x = (-7 +
) /2*1
x = (-7 +
) /2
x = (-7 +
)/ 2
x = -7 + 9 / 2
x = 2/2
x = 1
taking negative sign
(-b -
) /2*a
x = (-7 -
) /2*1
x = (-7 -
) /2
x = -7 -
/ 2
x = -7 - 4.12 / 2
x = -11.12/2
x = -5.56
therefore x = 1 , - 5.56
