Answer:
(-10,-6)
Step-by-step explanation:
(8 + b) / 2 = - 1
(8 + b) = - 1 * 2
8 + b = - 2
b+8-8 = -2 - 8
b = - 10
=====================
(a + 4)/2 = -1
(a + 4) = - 2
a + 4 = -2
a + 4-4 = - 2 - 4
a = - 6
Answer:
9.92
Step-by-step explanation:
8.63 x 1.15=9.92
Circumference = 3.1415 (pi) x diameter
44 = 3.1414 x diameter
Diameter = 14.006 or 14 (aprox)
Answer:
(6y+1)(6y-1)
Step-by-step explanation:
To do this question you must know what Difference of Two Squares is.
The Difference of Two Squares is two terms that are squared and separated by a subtraction sign.
You can simplify them like this below
a²- b² = (a+b)(a-b)
36y²-1
36y² can become 6y×6y.
1 can become 1×1.
So, plugging it into the formula above, you will get
<u>(6y+1)(6y-1)</u>
1)16^2 or 4^4
2)3^2
3)4^2
4)5^2
5)15^2
6)14^2
