We ordinarily expect a variable to be a single letter. This problem statement defines each variable using a double letter, so that is what we have used. (Sometimes Brainly doubles up variable content in copied text, so we suspect that may have happened here.)
Answer: 7
10
Explanation: First step is to shorten the fractions by finding the GCD (Greatest Common Divisor) of both numerator and denominator. For this example, GCD is 10. Then devide numerator and denominator with GCD:
70÷10 - 7
100÷10 - 10
Answer:
3b(2a+1)(2a-1)
Step-by-step explanation:
12a²b-3b
3b(4a²-1)
3b{(2a)²-1²)}
3b(2a+1)(2a-1)
Answer:
Eight pieces
Step-by-step explanation:
Create a number line running from 0 to 4/6.
Label the divisions as 1/6, 2/6, 3/6, and 4/6.
Divide each section in half to get small pieces of length 1/12.
Starting at zero, move to 4/6 on the number line and count the number of pieces as you go.
You count eight pieces, so Dario has eight pieces of rope.
Answer:
Triangle AEC
Step-by-step explanation:
Triangle ABD seems to be congruent to triangle AEC, because AD looks like it's equal to AC, AB looks like it's equal to AE, and BD looks like it's equal to EC, satisfying the criteria for an SSS congruence. Of course you could also go by the angles for SAS, SAS or AAS.
