Answer:

-36

Step-by-step explanation:

They gave you the numerical value of h. Think of h as just a placeholder. So each time you see h, you replace it with its numerical value. This is true for all letters such as the famous x and y.

<u>Replace h with -6</u>

2(-6) + 4(-6) = -36

In triangle △ABC, ∠ABC=90°, BH is an altitude. Find the missing lengths. AH=4 and HC=1, find BH.

Rudik [331]

Answer:

Length of BH is 2 units.

Step-by-step explanation:

We have, ΔABC with ∠ABC = 90° and an altitude BH.

Also, it is given that the length of sides AH is 4 units and HC is 1 units.

Since, the 'Altitude Rule' states that 'the length of the altitude is the geometric mean of the line segments it bisects'.

So, we get that,

$BH^{2}=AH\times HC$

i.e. $BH^{2}=4\times 1$

i.e. $BH^{2}=4$

i.e. $BH=\pm 2$

Since, the length of the side cannot be negative.

So, length of BH is 2 units.

Please i need help whats 1/5x - 2 = 4

$\frac{1}{5} x - 2= 4 \\$

Add sides 2

$\frac{1}{5} x - 2 + 2 = 4 + 2 \\$

$\frac{1}{5} x = 6 \\$

Multiply sides by 5

$5 \times \frac{1}{5} x = 5 \times 6 \\$

$x = 30$

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$\frac{1}{5x} - 2 = 4 \\$

Add sides 2

$\frac{1}{5x} - 2 + 2 = 4 + 2 \\$

$\frac{1}{5x} = 6 \\$

Inverse both sides

$5x = \frac{1}{6} \\$

Divide sides by 5

$\frac{5x}{5} = \frac{1}{6} \div 5 \\$

$x = \frac{1}{6} \times \frac{1}{5} \\$

$x = \frac{1}{30} \\$
