A triangle has a base of 10 inches and a height of 4.5 inches. What is the area of the triangle in square inches?

22.5

Step-by-step explanation:

10 x 4.5 = 45 divided by 2 is 22.5

22.5inch²

Step-by-step explanation:

area of a triangle = 1/2 base × height

base = 10 inches, height = 4.5inches

area = 1/2× 10 × 4.5

area = 5×4.5

area = 22.5inch²

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
