Answer:
X= -13
Step-by-step explanation:
Answer: $3.60
Explanation:
2.40 ÷ 8 = 0.3 (3 cents per slice)
0.3 x 12 = 3.60
Answer:
A: 34 degrees
B: 102 degrees
Step-by-step explanation:
Complementary angles = 90 degrees
Supplementary angles = 180 degrees
(a) 90 - 56 = 34
(b) 180 - 78 = 102
Remember:
The product of the sum of two perfect cubes:
a³ + b³ = (a + b)(a² - ab + b²)
The product of the difference of two perfect cubes:
a³ - b³ = (a - b)(a² + ab + b²)

Remember to follow PEMDAS.
(5c)(5c) = 25c²
(5c)(-2/3) = -10c/3
(2/3)(5c) = 10c/3
(2/3)(-2/3) = -4/9
25c²- 10c/3 + 10c/3 - 4/9
Combine like terms
25c² (-10c/3 + 10c/3) - 4/9
25c² - 4/9
25c² - 4/9 is your answer
hope this helps
Answer:
Step-by-step explanation:
We are given the equations
We need to combine like terms. As there are no exponents or numbers outside the parenthesis, we can just drop them and add all like terms
