I’m not rlly sure if i did it right & i’m sorry if i didn’t. i used the FOIL method
f= first to first
o=outer to outer
i=inner to inner
l= last to last
so it’d be
8b + 6b = 14b (f)
8b+ 8=16b(o)
-7+6b=-1b(i)
-7+8(l)
and then you add like terms so
[14b+16b-1b]+1
= 29b+1

liberstina [14]

Answer:

The corn plant grew by 11.17 inches during week 2.

Step-by-step explanation:

7 and 1/3 inches tall at the end of Week 1.

The height at the end of week 1, as a simple fraction, is:

7 + \frac{1}{3} = \frac{3*7 + 1}{3} = \frac{22}{3}

The corn plant was 18 1/2 inches tall at the end of Week 2.

At the end of week 2, the height will be of:

18 + \frac{1}{2} = \frac{18*2+1}{2} = \frac{37}{2}

How many inches did the corn plant grow during Week 2?

Height at the end of week 2 subtracted by the height at the end of week 1. So

\frac{37}{2} - \frac{22}{3} = \frac{3*37-2*22}{6} = \frac{67}{6} = 11.17

The corn plant grew by 11.17 inches during week 2.

2x - 3 + 23 + 128= 180
jek_recluse [69]

Answer:

x = 16

Step-by-step explanation:

2x - 3 + 23 + 128= 180

Combine like terms

2x+148 = 180

Subtract 148 from each side

2x+148-148= 180-148

2x =32

Divide by 2

2x/2 =32/2

x = 16
