Answer:
Distributive Property
Step-by-step explanation:
Answer choice a is correct because you are distributing 2 to each term in the parentheses. When you multiply 2 to each factor in the parentheses, it simplifies to 2x-2, thus making the new equation 6x+2x-2=30
Answer:
Step-by-step explanation:
I think your question is missing the key information about the degree of the big angle. So please have a look at the attach photo below, it may help you.
the measure of angle ABD = ∠ABC - ∠DBC
= 109 - 55
= 54 degree
Answer:
10
Step-by-step explanation:
You can get the three consecutive integers by using <em>algebraic expressions.</em>
Let's solve.
Let x be the <u>smallest even integer</u>.
Let x+2 be the second even integer.
Let x+4 be the largest even integer.
- x =

Therefore, 10 is the smallest even integer.
x+2 = 10+2 = 12
The second even integer is 12.
x+4 = 10+4 = 14
The largest even integer is 14.
Let's check by adding the three even integers.
10+12+14 = 36
36 = 36
<em>It's correct. </em>
The Length of the play ground is 15 meter. The width is 5 meters. 15x5=75 and since 15 is 3x larger than 5 they should be the numbers we are looking for here.
So 15+15+5+5= 40 the perimeter of the playground should be 40 meters.
I hope this helps!
