Ilya [14]3 years ago

Answer:

see explanation

Step-by-step explanation:

Given

A = \frac{1}{2} bh

a. substitute b = 6 and h = 5 into the formula

A = \frac{1}{2} × 6 × 5 = \frac{1}{2} × 30 = 15 units²

b.

Multiply both sides of the formula by 2

2A = bh, that is

bh = 2A ← divide both sides by b

h = \frac{2A}{b} = \frac{2(16)}{4} = \frac{32}{4} = 8

c

Using

bh = 2A ← divide both sides by h

b = \frac{2A}{h} = \frac{2(12)}{4} = \frac{24}{4} = 6

What is the point of intercection of lines y=x and y=2x+1
12345 [234]

Answer:

(-1, -1)

Step-by-step explanation:

Let's set these two equations equal to each other to solve the system:

x = 2x + 1

Solving for x, we get x = -1

Plug this value of x back into any of the two equations to get y: y = 2 * (-1) + 1 = -1.

Thus, the point of intersection is (-1, -1).

Hope this helps!

Name the property of real numbers illustrated by the equation.
Julli [10]

Answer:

Distributive property

Step-by-step explanation:

The distributive property states a(b+c)=a*b+a*c. This property states that when you multiply more than one thing, you must be sure to multiply everything. When you order fast food combos, you do the distribution property to receive the correct order.

If I order 3 Happy Meals, then I will receive

3(hamburgers +fries + drinks +toys)

3 hamburgers+3 fries+3 drinks+3 toys.

If I don't, then I have broken the distribution property.
