8x - (5x + 4) ≥ -31
8x -5x - 4 ≥ -31
3x ≥ -31 + 4
3x ≥ -27
x ≥ - 9
Answer: a numbe line with a circle on - 9 and shading to the left.
Because that drawing represents the number that are less or equel than -9 and the answer is the numbers greater or equal than -9.
Answer:
18 feet
Step-by-step explanation:
9/12 = 0.75
24 x 0.75 = 18
Answer:
Step-by-step explanation:
a. a^4 - 2ab^2 - 2ab^2 + 4b^4 = a^4 - 4ab^2 + 4b^2
b. 49x^2 - 14x + 1
c. 25a^2 - 20ab^4 + 4b^8
d. x^2 - 144
e. -16n^6 - 28n^3 + 28n^3 + 49 = -16n^6 + 49
Answer:
132
Step-by-step explanation:
That is an 180 degree angle so just do:
180-42=a
a=132
Answer:
64 + 64sqrt(3)
174.9 cm²
Step-by-step explanation:
AD/2 = 8cos(60) = 4
AD = 8 cm
Height of each triangle = 8sin(60)
= 4sqrt(3)
sqrt: square root
Area = 8² + 4(½ × 8 × 4sqrt(3))
= 64 + 64sqrt(3) cm²
= 174.8512517 cm²
