15 less than twice a number g is 19. Find g.

Helga [31]

Answer:

Step-by-step explanation:

15 less than twice a number g is 19

2g - 15 = 19 <em>add 15 to both sides</em>

2g - 15 + 15 = 19 + 15

2g = 34 <em>divdie both sides by 2</em>

2g : 2 = 34 : 2

g = 17

The height of a triangle is twice the length of its base. The

lions [1.4K]

Answer:

height = 14.2 m , base = 7.1 m

Step-by-step explanation:

let the base be b then height h = 2b

The area (A) of a triangle is calculated as

A = $\frac{1}{2}$ bh

Here A = 50 , then

$\frac{1}{2}$ × b × 2b = 50

b² = 50 ( take square root of both sides )

b = $\sqrt{50}$ ≈ 7.1 ( to the nearest tenth )

Then base = 7.1 m and height = 2 × 7.1 = 14.2 m

Root 8 + 3 root 32 - root 50

lisov135 [29]

$\sqrt{8} + 3 \sqrt{32} - \sqrt{50}$

$= \sqrt{4 \times 2} + 3 \sqrt{16 \times 2} - \sqrt{25 \times 2}$

$= 2\sqrt{ 2} + 12 \sqrt{2} - 5\sqrt{ 2}$

$= 9\sqrt{ 2}$
