Which expression is equivalent to 7a - 8 - 12a + 4?
I need step by step
Answer: First of all, add up the expressions with the same variables and the numbers.
7a-8-12a+4
=7a-12a-8+4
=-5a-4
or
=-(5a+4)
Both of them can be counted ans equivalent expression since all three of them works the same. Only the expression(way of writing) seems different.
Answer:
_ 5a - 4
Step-by-step explanation:
Combine Like Terms:
=7a + − 8 + −12a + 4
=( 7a + −12a ) + (− 8 + 4 )
=− 5a - 4 Answer!

Evaluate : 36.36 - 4x when x = 9
Answer: .36
Step-by-step explanation: If you follow PEMDAS the first step you would do is multiply 4 x 9 which gives you 36. Next, you subtract 36.36 - 36 which gives you your final answer of .36
[tex]\longrightarrow{\green{0.36}}[/tex]
[tex]\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}[/tex]
[tex]36.36 - 4x[/tex]
Substituting [tex]x[/tex] = 9 in the above expression, we have
[tex]=36.36 - 4 \times 9 \\ \\ = 36.36 - 36 \\ \\ = 0.36[/tex]
Note:-[tex]\sf\red{PEMDAS\: rule.}[/tex]

D = Division

B : area = 18
36 =2x18
36= 3x12
36=4x9
The triangle can have dimensions in the form of bxh in 36 =2x18 or 36= 3x12 or 36=4x9

Write an algebraic expression to represent the following phrase:
the sum of a number and 0.5
no links
Answer:
x + 0.5
Step-by-step explanation:
The sum of implies that addition is involved.
Since the number is unknown, you use a variable. For example, x.
You're adding x and 0.5 so you would use a plus sign.
The algebraic expression would be x + 0.5.
Hope that helps.

A net of a square pyramid is shown below. What is the surface area, in squared centimeters, of the pyramid?
A. 60.7
B. 86.7
C. 121.4
D. 147.4
Answer:
[tex]\text{B. }86.7}[/tex]
Step-by-step explanation:
The total surface area of the square pyramid consists of one square and four congruent triangles. By adding the total area of each, we get the total surface area of the square pyramid.
Area of the square: [tex]5.1^2=26.01[/tex]
Area of four triangles: [tex]4\cdot \frac{1}{2}\cdot 5.95\cdot 5.1=60.69[/tex]
Therefore, the total surface area of the pyramid is [tex]26.01+60.69=\boxed{\text{B. }86.7}}[/tex]
