Answer:

Explanation:

a). 7(2x - 3)
= 7(2(4) - 3)
= 7(8 - 3)
= 35

b). (x + y)^2 - 3x
= (4 + 3)^2 - 3(4)
= 49 - 12
= 37

a). 2x x y
= 2(26) x 3b^2
= 52 x 3b^2
= 156b^2

b). mn/k
= 5a^5b x 4ab^3/10a^4b^3
= 20a^6b^3/10a^4b^3
= 2a^2

Angle x is such that sin x = a + b and cos x = a − b, where a and b are constants.
Mazyrski [523]

Answer:

Step-by-step explanation:

sin x=a+b

cos x=a-b

sin²x+cos²x=(a+b)²+(a-b)²=2a²+2b²

or 2a²+2b²=1

a²+b²=1/2 which is constant for all values of x

(ii)

\frac{\sin x}{\cos x}=\frac{a+b}{a-b}\\\tan x=\frac{a+b}{a-b}=2\\a+b=2a-2b\\b+2b=2a-a\\or a=3b

On this note, only 2 numbers are a units away from zero according to the given condition.
