Answer
Expressions 4(x+5) and 5(x+4) are Equivalent
Expressions 5(2m+2) and 10m+10 are not equivalent
Step-by-step explanation:
Heres why,
4(x+5) and 5(x+4)
4 times x =4x, so multiply 4x by 5 which should give you 20.
and multiply 5 to x which would be 5x and multiply that to 4 which would be 20, they match up so they are Equivalent.
5(2m+2) and 10m+10
times 5 to 2m to get 10m and times 10m by 2 to get 20.
10m+10 = 1 which they are not equivalent
Answer:
480
Step-by-step explanation:

Answer:
x=54
Step-by-step explanation:
these two angles are supplementary to each other. this is because alternate interior angles are congruent, and 2x+42 degrees is supplementary to the alternate interior angle of x-24 degrees. so, we can add these two numbers up and set it equal to 180.
2x+42+x-24=180
3x+18=180
3x=162
x=54
if this question is asking for x, 54 is the answer. if it is asking for the angle measures, plug in 54 for x for each angle and solve.
Answer:↓↓↓
Step-by-step explanation:
We are given that side AB is congruent to <u>BD</u>. We are also given that side AC is congruent to <u>CD</u>.
We know that side BC and side <u>CB</u> are congruent because of the <u>Reflexive</u> property.
Therefore, ΔABC and Δ<u>DBC</u> are congruent because of <u>SSS Postulate</u>.
Hope this helped!
