Answer:
pick number 3
Step-by-step explanation:
Answer:
A) what did the student do wrong, explain why they are incorrect
B) Demonstrate and explain the correct way to answer the question.
Lauren says that two expressions 3x+4(2x+5) and 6x +5x +5 are equivalent. Simplify the expressions to determine whether or not Lauren is correct. Substitute a value for x to see if she is right.
<u>3x+8x+20 = 6x+5x+5</u>
<u>11x+20 = 11x+5</u>
<u>She is wrong</u>
Students answer: She is correct because both equal 11x +5. I substituted x=2 and got 27 for both
<u>She is wrong because 27 will be the answer for ' 11x+5' only. The correct method should be </u>
<u>x=-15 </u>
Step-by-step explanation:
Answer:
b) y=2x-3 y-int.=-3 x= 1/2 (think of rise over run)= up 2 over 1. C) IDK D) y=2/4+3 E)7/2-8
Step-by-step explanation:
<h2>when you solve in slope intercept form ex. 3x+4y=12 move 3x by subtracting to the other side. 3x-3x=0 cancel then your left with 4y=-3 (you moved to both sides)+ 12 divide the equation by 4. left with 4divided by 4 cancels left with y= -3+12 divided by 4= y=3/4+8</h2><h2 /><h2>Remember if positive subtract if negative number add to both sides.</h2>
Answer:5
Step-by-step explanation: the like moves at and angle bc u started going faster due to running
Answer:
24
Step-by-step explanation:
SA= 6a sqaured
a is the edge
a=2
a squared = 4
SA=6(4)
SA=24
