Answer:
Yes it is
Step-by-step explanation:
4d + 3d = 7d so 7d + 15 would be the expression for both except it would only be 3d + 4d = 7d and 7d + 15 is the same as the first expression that I got from evaluating 4d + (15 + 3d).
Answer:
She would use the mean.

Answer:
<h3>Find the solution below</h3>
Step-by-step explanation:
The expression is incomplete. Let say the expression is 4 (-2u + 7) = 44
Given the expression
4 (-2u + 7) = 44
Step 1: Open the bracket by distributing 4 over -2u and 7
4 (-2u + 7)= 44
4(-2u) + 4(7) = 44 (distributive property)
-8u + 28 = 44
Step 2: Subtract 28 from both sides
-8u + 28 - 28 = 44 - 28 (subtraction property of equality)
-8u = 16
Step 3: Divide both sides by -8
-8u/-8 = 16/-8 (division property)
u = -2
Step-by-step explanation:
Given that,
The area of a blackboard is 
The area of poster is 
We need to find the unit rate of the blackboard's area to the poster's area. So, it can be calcualted by dividing blackboard's area to the poster's area.
So,
So, the rate of 
.
Answer:
The answer to your question is letter A
Step-by-step explanation:
Polynomial 4x¹⁰ + 9x¹⁰
To sum or subtract polynomials, just look for like terms and do the operations considering the rules of signs.
In this problem both terms are like terms, then we add the coefficients and write the variable without a change.
4x¹⁰ + 9x¹⁰ = 13x¹⁰
