Answer:
Error: not
Solution:x=0 and 3
Step-by-step explanation:
We have to find the error and correct answer
Given:
Using the formula
Therefore, x=0 and x=3
But last step in the given solution
It is wrong this property is used when
then
Hence, the student wrote instead of and solution is given by
x=0 and x=3
Answer:
x = 27
Step-by-step explanation:
AC // DE
m∠ABD ≅ m∠BDE = 72°
m∠ADB + m∠BDE + m∠EDF = 180°
2x + 72° + 2x = 180°
4x = 108°
x = 27°
Answer:
5(11+7) = 55+35
Step-by-step explanation:
The distributive property states that when multiplying a term with a sum multiply into each term within the sum. Here you have a sum. You’ll reverse the distributive property by factoring our a term which could multiply into each. 55 and 35 both have 5 as a factor. This makes the expression 5(11+7) = 55+35.
Answer:
true
Step-by-step explanation:
if the width is w and the length is l then 6 more than the width is w+6 and that is equal to the length so l = w+6
5)
Based on graph x > -3
Answer: x > - 3 (last one)
6)
m> - 2
So the answer is the last one.
