Daniel expanded the expression as shown. What errors did he make? Select three options.
The first term should be negative.
The second term should be positive.
The last term should be -1 1/2, not -1 1/4
He added -8 and -2 instead of multiplying -8 by -2
He did not simplify the expression completely.
Mark this and return

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

2 2/3 hours duhh silly

step-by-step explanation:

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)

110

step-by-step explanation:

based on the question i am guessing that it is a typo for abc
