What is 2x-4+3x+2=48
Answers
Answer: x = 10
Step-by-step explanation: First, you combine like terms. Your equation is now 5x-2 = 48. Then, you isolate the variable by moving the -2 onto the other side. Now your equation is 5x = 50. Then you divide 5x by 5 to isolate x and divide 50 by 5 and get 10, so x = 10.

In this question figure of pyramid is attached below the question .
Surface area of the rectangular pyramid :
Area of the Base = Length × Width
= 10 × 2 = 20 cm²
Area of Lateral #1 =
=
= 31.5 cm²
Area of Lateral #2 =
=
= 8 cm²
Surface area of the pyramid = 20 + 2(31.5) + 2(8)
= 20 + 63 + 16
= 99 cm²
Surface area of the pyramid is 99 cm²
Answer:
99cm2

F: 4x*2x = 8x^2
O: (4x)*3 = 12x
I : 8*2x = 16x
L: 8*3 = 24
End of First step
========================
Just in case you want the answer
8x^2 + 28x + 24
And to take out the common factor
4(2x^2 + 7x + 6)
Answer:
(4x + 8) (2x+3)
FOIL
First- (4x)(2x)= 8x2
Outer- (4x) (+3)= +12x
Inner- (8) (2x)=16x
Last- (8) (+3)=+24

Answers
The confounding variable, often described as a confounder or confusing factor, is a dimension in studies looking at a possible causation link, and further calculation can be defined as follows:
- It has connected both to the study's apparent cause and its ostensible impact.
- It can be difficult to differentiate between both the genuine relationship between the independent variable and the effect of a contextual factor.
- It is an external factor that alters the impact of variables to utilized to sway the findings of an experiment.
Therefore, the final answer is "Confounding variable".
