Answer:

$x = 18$

Step-by-step explanation:

Given

$\frac{x}{6} - 7 = -4$

Required

Solve for x

$\frac{x}{6} - 7 = -4$

Add 7 to both sides

$\frac{x}{6} - 7+7 = -4+7$

$\frac{x}{6} = -4+7$

$\frac{x}{6} = 3$

Multiply through by 6

$6 * \frac{x}{6} = 3 * 6$

$x = 3 * 6$

$x = 18$

mart [117]

The answer of $sin^2 (pi/4) + cos^2 (pi/4)$ is √ 2

<u>Step-by-step explanation:</u>

The value of $sin^2 (pi/4)$ = √2/ 2

The value of $cos^2 (pi/4)$ = √2/ 2

= √2/ 2 + √2/ 2

= √2 + √2 / 2

= 2 √2 / 2

Dividing √2 by 1

= √2
