The height of a triangle is 4 inches greater than twice its base. The area of the triangle is no more than 168 in.² which inequa

Gennadij [26K]

<h2>Answer:</h2>

Correct option: B

<h2>Step-by-step explanation:</h2>

When we say a is no more than b, we express this in a mathematical language as follows:

$a\leq b$

In this inequality, we know that the area of the triangle is no more than 168 in². In other words, if the area is named $A$ , then:

$\mathbf{(1)} \ A\leq 168$

We also know that the height of a triangle is 4 inches greater than twice its base. Translating this in a mathematical language:

$\mathbf{(2)} \ h=2b+4 \\ \\ h:height \ of \ the \ triangle \\ \\ b:base \ of \ the \ triangle$

From geometry, we know that the area of a triangle is given by:

$\mathbf{(3)} \ A=\frac{bh}{2}$

Matching (1), (2) and (3):

$\frac{bh}{2}\leq 168$

Since the length of the base of the triangle is $x$ , then $b=x$

$\frac{x(2x+4)}{2}\leq 168 \\ \\ Common \ factor \ 2: \\ \\ \frac{2x(x+2)}{2}\leq 168 \\ \\ \boxed{x(x+2)\leq 168}$

Finally, correct option is B.

<em>Greetings from Brasil...</em>

Here is the problem:

[(15X - 8)/3] + [(9X - 3)/2]

<em>Let's multiply everything by 6</em>

[6.(15X - 8)/3] + [6.(9X - 3)/2]

[2.(15X - 8)] + [3.(9X - 3)]

30X - 16 + 27X - 9

<h3>57X - 25</h3>

Which is the area of a triangle with a base of 10 inches and a height of 3 inches

klio [65]

Answer:

area = 15 in²

Step-by-step explanation:

The area (A) of a triangle is calculated using the formula

A = $\frac{1}{2}$ bh ( b is the base and h the height )

here b = 10 and h = 3, hence

A = $\frac{1}{2}$ ×10 × 3 = 15 in²
