Tyler is simplifying the expression 6−2x+5+4x . Here is his work: 6−2x+5+4x

(6−2)x+(5+4)x

4x+9x

13x

a. Tyler’s work is incorrect. Explain the error he made.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

positive

step-by-step explanation:

the quadrant is facing upwards

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
