The answer is 26 but if you are talking about absolute value it is still 26
Answer:
x = 0, x = 3
Step-by-step explanation:
Given
- 4x² = - 12x ( add 12x to both sides )
- 4x² + 12x = 0 ← factor out - 4x from each term
- 4x(x - 3) = 0
Equate each factor to zero and solve for x
- 4x = 0 ⇒ x = 0
x - 3 = 0 ⇒ x = 3
Answer:
x = 4
y = 10
Step-by-step explanation:
29x - 3 + 15x + 7 = 180 (Linear Pair)
44x + 4 = 180
44x + 4 = 180 - 4
44x = 176
x = 4
29(4) - 3
116 - 3
113
13y - 17 = 113 (Alternate Exterior Angles Theorem)
13y - 17 + 17= 113 + 17
13y = 130
y = 10

Answer:
60
Step-by-step explanation:
perimeter (p) = 8 + 17 + 15 = 40
semi-perimeter (s) = p/2 = 20
Area = square root of s(s-a)(s-b)(s-c) where a,b,c are the sides of the triange by Herons formula.
Therefore, area = 20(20-8)(20-15)(20-17) = square root of 3600 = 60
