Which of the following can be the side lengths of a triangle?

1 answer:

3 0

To solve this question, we need to know the triangle inequality property, which states that the sum of two legs of a triangle is always greater (it can't be equal to) than the third leg. Using this property, we can deduct that the only answer that works is A, 6,6, and 5.

For f(x) = 2x+1 and g(x) = 3x-7, find (f-g)(x)

marissa [1.9K]

Answer:

(f - g)(x) = -x + 8

General Formulas and Concepts:

Order of Operations: BPEMDAS

Step-by-step explanation:

Step 1: Define

f(x) = 2x + 1

g(x) = 3x - 7

(f - g)(x) = f(x) - g(x)

Step 2: Simplify

Set up: (f - g)(x) = (2x + 1) - (3x - 7)
Distribute -1: (f - g)(x) = 2x + 1 - 3x + 7
Combine like terms: (f - g)(x) = -x + 8

Look at the figure shown below:

kow [346]

Answer: b) two sides and the included angle are congruent

Step-by-step explanation:

RS = QS SIDES are congruent

∠PSR ≡ ∠PSQ ANGLES are congruent

PS = PS SIDES are congruent

ΔPSR ≡ ΔPSQ by the Side-Angle-Side (SAS) Congruency Theorem

Since we know the triangles are congruent, we can state that their parts are congruent:
