Answer:
a=-8 b=2
Step-by-step explanation:
x^2+6x-16
x^2+(8-2)x-16=0
x^2+8x-2x-16=0
X(X+8)-2(X+8)=0
(X+8)(x-2)=0
Compare with (X+a)(X+b)
Where we get a=-8 b=2
Answer:
C=89.2
Step-by-step explanation:
The formula of the circumference of a circle is C=2piR (or C=piD). Now, when calculating, plug in the numbers, giving you C=2pi14.2. Multiply everything, you get a super long irrational number; just round. You will get 89.2.
Multiply 9 and 5 then multiply by .5 giving you 22.5 so I’d say that’s your best option
To resolve this exercise you have to choose two numbers that when you multiply them, you get 64:
For Set 1: If you choose to make a square frame, you can calculate its dimensions by clearing the value of each sides of it from the formula of the area of a square:
A= L²
L= √A
L= √64 inches²
L= 8 inches
So, you have a square frame of 8 inches x 8inches = 64 inches²
Set 1: 8 inches x 8 inches
For set 2, you can make a rectangular frame with the following dimensions: 16 inches x 4 inches = 64 inches²
Set 2: 16 inches x 4 inches
