Share Answer Let C n G = X
n C only = 40 - x
n G only = 30 - x
40 - X + 30 - X = 50
70 - X = 50
X = 70 - 50
X = 20

Share Answer

x2 + 3x2

2x - 8

=	x(x2+3x10)
	2(x2-4)

=	x(x+5)(x-2)
	2(x2-2 2)

=	x(x+5)(x-2)
	2(x-2)(x+2)

=	x(x+5)
	2(x+2)

Share Answer y x
y = Kx
K = ^y/_x = ³/₁₆
= ³/₄
y = ³/₄x
= ³/₄64 when x = 64
= ³/₄ x ⁸/₁
= 6

Share Answer x * y = x + y²
2 * 3 = 2 + 3²
= 2 + 9
= 11
(2 * 3) * 5 = 11 + 5²
= 11 + 25
= 36

Share Answer Using substitution If 18(p+18) = (18 + p)q
let q = 18
imply 18(p+18) = (18+p)18
i.e 18p + 18 x 18 = 18 x 18 + 18p
Since the left hand side = the right hand side
imply that q = 18

Share Answer \(\left[\begin{array}{cc}
x & 3\\
2 & 7\end{array}\right]\)= 15
x x 7 - 2 x 3 = 15
7x - 6 = 15
7x = 15+6
7x = 21
x = ²¹/₇
x = 3

Share Answer RTS = 90^o ( in semi circle)
UTS = 25^o ( in alternate segment)
X + 90 + 25 = 180(sum of s on a str line)
X + 115 = 180
X = 180 - 115
X = 65^o
