the answer to your question is 2
B: –3a^2 + 11a + 5
C: 3a^2 + 11a + 5
D: –3a^2 + 11a – 5
Answer: B = –3a^2 + 11a + 5
For difference, the answer is
-3a^2 -5a -5
Step-by-step explanation:
(3a – 3a^2) + (5 + 8a)
To find the sum or difference, we will open the brackets.
To look for l the sum, we add
3a – 3a^2 + 5 + 8a
Collecting like terms,
= -3a^2 +8a + 3a +5
= -3a^2 + 11a + 5
Option B is the right answer.
To look for the difference, we subtract.
(3a – 3a^2) - (5 + 8a)
Opening the brackets
3a – 3a^2 - 5 - 8a
Collecting like terms
-3a^2 + 3a -8a -5
= -3a^2 -5a -5
The options available corresponds only to what we got for the sum, so
-3a^2 + 11a + 5 is the answer
1.) Remove parentheses.
3a−3a^2 +5+8a
2.) Collect Like Terms.
(3a+8a) - 3a^2+5
3.) Simplify.
11a - 3a^2+5
The box weighs 25 grams.
Each cake weighs the same.
What does each cake weigh? |
grams.
Help!!!
Answer:
35g
Step-by-step explanation:
given,altogether 300g
box weight is 25 gram
know we know that
1 cake weight and box =300/5
1 cake weight =60 gram -25gram
cake weight =35g
Answer:The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis
Step-by-step explanation:
The value of y will be y = 78 - 12 x.
An expression , 13 = 1/6y + 2x is given.
We have to solve the expression to find out the value of y.
What is algebra ?
Algebra is the branch that deals with various symbols and the arithmetic operations such as multiplication , division , etc.
As per the question ;
The expression given is ;
13 = 1/6y + 2x
Let's solve it to get the value of y ;
So ,
13 = 1/6y + 2x
or
1/6y = 13 - 2x
multiplying both RHS and LHS by 6 , we get ;
y = 78 - 12 x
Thus , the value of y will be y = 78 - 12 x.
