Answer:

Step-by-step explanation:

By equa tion of area of triangle: S = 1/2 * height * base

Triangle B: 32 = 1/2 * 8 * x --> x = 8 (cm)

The base of triangle A is half of the base of triangle B so it is 4 cm.

The area of triangle A = 1/2 * 8 * 4 = 16 (cm2)

How do you calculate the common difference?

SCORPION-xisa [38]

Answer:

<h3> second term minus first term </h3>

Step-by-step explanation:

Difference is a result of subtracting (not dividing!)

To calculate difference between two terms we have to subtract the previous from the next:

$d=a_2-a_1=a_3-a_2=a_4-a_3=...=a_n-a_{n-1}$

Solve this system of equations.<br>y=2x-5<br>y=-2x+3

Alinara [238K]

Answer:

x = 2

y = -1

Step-by-step explanation:

y = 2x - 5

y = -2x + 3

2x - 5 = -2x + 3

4x = 8

x = 2

y = 2(2) - 5

y = -1
