So the formula for area of a triangle is base * height / 2.

(In this case the height could be the altitude)

So if we rotate the shape, so line AC is the base, we can therefore clearly see what the height and length are.

If we count it, the line AC would equal 5 segments and the line BD would equal 3 segments.

So, 5 * 3 / 2

Or,

15/2

Which is 7.5.

So your answer is 7.5 square units.

Question 3 Review your answers to Question 2. What happens to the coordinates of a shape when the shape reflects about the x axi

Slav-nsk [51]

Answer:

When the shape reflects about the x-axis, the x-coordinate is unchanged but the y-coordinate becomes negative. When the shape reflects about the y-axis, the y-coordinate is unchanged but the x-coordinate becomes negative.

How do you solve this? 18 " n=21

dalvyx [7]

$18 ^{n} =21$

$log(18) ^{n}=log(21)$

$n*log(18)=log(21)$

$n= \frac{log(21)}{log(18)}$

$n=1.053$

Given the functions, fx) = x - 8 and g(x) = x2 + x - 1, perform the indicated operation. When applicable, state the domain

adell [148]

Answer:

A

Step-by-step explanation:

(fg)(x) = f(x) × g(x)

= (x - 8)(x² + x - 1)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x² + x - 1) - 8(x² + x - 1) ← distribute both parenthesis

= x³ + x² - x - 8x² - 8x + 8 ← collect like terms

= x³ - 7x² - 9x + 8 → A

There are no restrictions on the domain.

P-21=34 P=34-21 P=13<br>What is the value of p?<br>

vredina [299]

Simplifying

P + -21 + -21 = 34 + -21

-21 + -21 + P = 34 + -21

Combine like terms: -21 + -21 = -42

-42 + P = 34 + -21

Combine like terms: 34 + -21 = 13

-42 + P = 13

Solving

-42 + P = 13

Solving for variable 'P'.

Move all terms containing P to the left, all other terms to the right.

Add '42' to each side of the equation.

-42 + 42 + P = 13 + 42

Combine like terms: -42 + 42 = 0

0 + P = 13 + 42

P = 13 + 42

Combine like terms: 13 + 42 = 55

P = 55

Simplifying

P = 55
