A student solved 3x−4=x7 in six steps, as shown.

Step 1: 3=x(x−4)7
Step 2: 21=x(x−4)
Step 3: 21=x2−4x
Step 4: 0=x2−4x−21
Step 5: 0=(x−7)(x+3)
Step 6: x=−3, x=7
Which statement is an accurate interpretation of the student's work?

A The student solved the equation correctly.

B The student made an error in step 2.

C The student made an error in step 5.

D Only x=7 is a solution to the original equation.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

answer: dead jah

step-by-step explanation:

bullet + jah= dead jah

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
