The triangles are similar, they aren't congruent (identical) though as we don't know if they share a common side
Answer:
It would be C, 64.387
Step-by-step explanation:
First, you have to solve 7x1/1000. This equal to 7/1000 which should be converted into decimal form (since all the answers are in decimal form). 7/1000 is 0.007 in decimal form.
It is 0.007 since in 7/1000, the denominator is 1000, making 7 in the thousandths place (the 3rd digit to the right of the decimal point).
The only number that contains 0.007 is the 3rd one, making it your answer.
Answer:
Step-by-step explanation:
First, extract the greatest common factor of the numerical as well as the variable parts:
the GCF of 5 and 80 is "5", and the GCF between 
and 
is , then:
Now, we can re-write the binomial in parenthesis as a difference o squares to be able to factor out even further:
we now repeat the process for the binomial difference:
So finally the complete factorization is:
Answer:
<h2>2.) When dividing by −2, he did not change the direction of the sign. </h2>
Step-by-step explanation:
-4(x + 8) ≤ -2x + 50 <em>use the distributive property: a(b + c) = ab + ac</em>
-4x - 32 ≤ -2x + 50 <em>add 2x to both sides</em>
-4x + 2x - 32 ≤ -2x + 2x + 50
-2x - 32 ≤ 50 <em>add 32 to both sides</em>
-2x - 32 + 32 ≤ +50 + 32
-2x ≤ 82 <em>divide both sides by (-2) / </em><em>flip the inequality sign</em><em>/</em>
x ≥ -41
Andrew's mistake:
2.) When dividing by −2, he did not change the direction of the sign.
<span>The quotient is 6 and remainder is 6, because 8 goes into 52 6 times and that equals 48. Since 52-48=4, the remainder is 4.</span>
