Answer:

(-\infty,-2] \cup [\displaystyle\frac{-4}{3},-\infty)

Step-by-step explanation:

We are given the following information in the question:

We have to solve the given inequalities for x:

Inequality 1

-9x+5 \leq 17\\-9x \leq 17-5\\-9x \leq 12\\\\x \leq \displaystyle\frac{12}{-9}\\\\x \geq \frac{-4}{3}\\\\x \in [\frac{-4}{3},-\infty)

Inequality 2

13x + 25 \leq -1\\13x \leq -1-25\\13x \leq -26\\\\x \leq \displaystyle\frac{-26}{13}\\\\x \leq -2\\x \in (-\infty,-2]

The combined solution for both the inequalities is given by:

(-\infty,-2] \cup [\displaystyle\frac{-4}{3},-\infty)

Answer:

(-∞ 2] ∪ [-4/3 ∞ )

Step-by-step explanation:

Given compound inequality,

-9x+5\leq 17\text{ or }13x+25\leq -1

-9x\leq 12\text{ or }13x\leq -26  ( Subtraction property of inequality )

-x\leq \frac{12}{9}\text{ or }x\leq -\frac{26}{13}   ( Division property of inequality )

-x\leq \frac{4}{3}\text{ or }x\leq -2

x\geq -\frac{4}{3}\text{ or }x\leq -2   ( a < b ⇒ - a > - b )

Hence, the solution of the given inequality is,

(-∞ -2] ∪ [-4/3 ∞ )

Option C: 5 x(4 x+7)(3 x+2) is the possible expressions for length, width and height of the prism.

Explanation:

The volume of the rectangular prism is 60 x^{3}+145 x^{2}+70 x

To determine the length, width and height of the rectangular prism, let us factor the expression.

Thus, factoring 5x from the expression, we have,

5 x\left(12 x^{2}+29 x+14\right)

Let us break the expression 12 x^{2}+29 x+14 into two groups, we get,

5x[\left(12 x^{2}+8 x\right)+(21 x+14)]

Factoring 4x from the term 12 x^{2}+8 x , we get,

5x[4 x(3 x+2)+(21x+14)]

Similarly, factoring 7x from the term 21 x+14 , we get,

5x[4 x(3 x+2)+7(3x+2)]

Now, let us factor out 3x+2, we get,

5 x(4 x+7)(3 x+2)

Hence, the possible expressions for length, width and height of the prism is 5 x(4 x+7)(3 x+2)

Therefore, Option C is the correct answer.

A triangle has side lengths of 39, 80, and<br> 87. Is this triangle a right triangle?
iren2701 [21]

Answer:

Step-by-step explanation:

39²=1521

80²=6400

39²+80²=1521+6400=7921

87²=7569

7921≠7569

so it is not aright angled triangle.
