Formula

The area of any triangle is

A = 1/2 * b * h

Givens

A = 10

b = 4

h = x + 3

Sub and solve

10 = 1/2 * 4 * (x + 3) Take 1/2 of 4

10 = 2 * (x + 3) Divide by 2

10/2 = 2( x + 3) / 2

5 = x + 3 Subtract 3 from both sides.

5 - 3 = x + 3 - 3

2 = x <<<<<<<<<<<<<< answer.

A = 1/2 b h where A = 10 b = 4 and h = x + 3

h = 2A/b

h = 2*10 / 4

h = 20/4

h = 5

h = x + 3

5 = x + 3

x = 2

Answer

x = 2

Answer:

${3}^{2}$

Step-by-step explanation:

$3^{ - 6} \times (3^4 \div 3^0)^2$

$\frac{1}{ {3}^{6} } \times ( {3}^{4} \div {3}^{0} {)}^{2}$

$\frac{1}{729} \times ( {3}^{4} \div {3}^{0} {)}^{2}$

$\frac{1}{729} \times ( {3}^{4} {)}^{2}$

$\frac{1}{729} \times 6561$

$\frac{1}{729} \times (729(9))$

$9$
