Simplify. please7−5x−(3+5x) 4 + 10x44−10x10 + 10x

Alenkasestr [34]

Simplify the expression:

7 - 5x - (3 + 5x)

Operate the parentheses. Each term changes its signs because the minus sign represents a -1:

7 - 5x - (3 + 5x) = 7 - 5x - 3 - 5x

Collect like terms:

7 - 5x - (3 + 5x) = 7 - 3 -5x - 5x

Simplify:

7 - 5x - (3 + 5x) = 4 - 10x

Answer: 4 - 10x

Use Heron's formula to find the area of the triangle. Round to the nearest square unit.

kakasveta [241]

Answer:

24.25 in²

Step-by-step explanation:

s = (a + b + c)/2 = (8 + 13 + 7)/2 = 14 in

s - a = 6, s - b = 1, s - c = 7

the area = $\sqrt{14\times6\times1\times7}=24.25$
