What is the area of the triangle in centimeters<br> squared?

Rashid [163]

Answer:

A = 112cm²

Step-by-step explanation:

Area of a triangle = (bh) / 2

b = base length and h = height

The triangle shown has a given base length of 14cm and a given height of 16cm

Hence area = ( 16 * 14 ) / 2

16 * 14 = 224

224 / 2 = 112

A = 112cm²

Asap solve problem please. Will give BRAINLIEST.

Vera_Pavlovna [14]

Answer:

5 ft, 6.5 ft, 7 ft

Step-by-step explanation:

area of trapezoid = (base1 + base2)h/2

Let the unknown base = x

area of trapezoid = (8.5 + x)(6)/2

area = 3x + 25.5

We want the area to be between 40 ft^2 and 48 ft^2.

40 < 3x + 25.5 < 48

14.5 < 3x < 22.5

4.8333 < x < 7.5

Answer: 5 ft, 6.5 ft, 7 ft

How do you solve an absolute value equation?

Mkey [24]

The distance between two real numbers $x,y$ is the absolute value of their difference, $|x-y|$ . So the statement "all $x$ that are 1/4 away from -6" is captured in the equation

$|x-(-6)|=\dfrac14$

$|x+6|=\dfrac14$

To solve, you can use the definition of absolute value: if $x$ is not negative, then $|x|=x$ ; otherwise, $|x|=-x$ .

So there are two cases to consider:

1. Suppose $x+6\ge0$ . Then $|x+6|=x+6$ , and the equation reduces to

$x+6=\dfrac14\implies x=-\dfrac{23}4$

2. Suppose $x+6$ . Then $|x+6|=-(x+6)=-x-6$ and

$-x-6=\dfrac14\implies x=-\dfrac{25}4$

$-6=-\dfrac{24}4$ , so the two solutions we found are correct because both $-\dfrac{23}4$ and $-\dfrac{25}4$ are indeed 1/4 away from -6.

- - -

For the question regarding inequality, you know that the absolute value must return a non-negative number. In other words, there is no $x$ such that $|x|$ .
