The side lengths form a triangle that is similar to triangle ABC will be 30, 21, and 45. Option A is correct.
What is the triangle?
In terms of geometry, a triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
It is found that the sides of the triangle are,
AB=10
BC=7
CA=15
In order for the triangle to similar the ratio of their sides is equal.
AB:BC: CA = 10:7:15
The ratio is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
AB:BC: CA = 10×3:7×3:15×3
AB:BC: CA =30, 21, 45
The ratio of the triangle for the given condition must be the same.
Thus, the side lengths that form a triangle that is similar to triangle ABC will be 30, 21, and 45. Option A is correct.

7a-3=8+6a
add 3 to both sides
7a=8+6a+3
7a=11+6a
subtract 6a from both sides
1a=11
you can just remove the 1 in front of the a
a=11
Answer=11
7a−3=8+6a
Let's solve your equation step-by-step.
7a−3=6a+8
Step 2: Subtract 6a from both sides.
7a−3−6a=6a+8−6a
a−3=8
Step 3: Add 3 to both sides.
a−3+3=8+3
So the Answer is
a=11

Answer:
C. as likely as not
Step-by-step explanation:
The teacher makes two groups with the same number and divides the student at random. The two groups have equal size, so the chance for someone to get picked into group 1 is 100%/2= 50%. The chance for someone to get picked into group 2 will be also 100%/2= 50%
The chance to get picked to be in group 1(50%) is the same as the chance to NOT get picked into group 1(50%). The word to explain this chance will be "as likely as not".

So, for your questions, the answers would look like this:
$8.98 rounds to $9.00, because 9 is bigger than 5.
$6.49 would round down to $6.00, because 4 is less than 5.
$2.51 rounds up to $3.00, because 5 is equal to 5.
$9.78 would round up to $10.00, because 7 is higher than 5.
$39.89 will round up to $40.00, because 8 is bigger than 5.
