Answer:
1.$3÷12=0.25
each egg would cost 25 cents
2.12×18=216
216×25=5,400
Answer:
(2a + 1)(2a - 5)
Step-by-step explanation:
Given
4a² - 8a - 5
Consider the factors of the product of the coefficient of the a² term and the constant term which sum to give the coefficient of the a- term
product = 4 × - 5 = - 20 and sum = - 8
The factors are + 2 and - 10
Use these factors to split the a- term
4a² + 2a - 10a - 5 ( factor the first/second and third/fourth terms )
= 2a(2a + 1) - 5(2a + 1) ← factor out (2a + 1) from each term
= (2a + 1)(2a - 5)
Answer:
Step-by-step explanation:
j
Answer:
9
Step-by-step explanation:
1. You would make these to equations equal to each other because there are parellel(they have the same angel)
2. EQUAL these 2 equations together to find r.
3. SOLVING for r
7r - 5 = 6r + 4
r = 9
