Answer:
A.
Step-by-step explanation:
Because I used the Internet.
:)
Ok well you would use pathagorean there so A2+B2=C2
Answer:
C)12 x 108 has the closest value.
Step-by-step explanation:
Firstly, (7 x 108) + (5 x 105) is equal to 756 + 525 which is equal to 1281.
A)7 x 108= 756
B)12 x 1013= 12156
C)12 x 108=1296
D)7 x 1013=7091
Factor
in form
ax²+bx+c form
use the ac method
1. mulitply a and c
2. factor the result such that the 2 factors add to b
3. split b into those 2 factors
4. group the terms
5. undistribute common factors
6. undistribute again
first multiply ac
4 times 5=20
now
what 2 numbers multiply to 20 and add to 12
2 and 10
4x²+2x+10x+5
group
(4x²+2x)+(10x+5)
undistribute
2x(2x+1)+5(2x+1)
undistribute the (2x+1)
(2x+1)(2x+5) is factored form whih you have there, nice
