Answer:
x=1
Step-by-step explanation:
-4-2(3-x)=-2(x+3)
Expand parentheses:
-4-6+2x=-2x-6
Add 2x+6 to both sides:
4x-4=0
Add 4 to both sides:
4x=4
Divide both sides by 4:
x=1
Hope this helps!
Answer:
f(3) = 12
Step-by-step explanation:
f(x) = 2x - 12 + 2x²
f(3) = 2(3) - 12 + 2(3)²
f(3) = 6 - 12 + 2(9)
f(3) = -6 + 18
f(3) = 12
Remember that x=3 is being substituted into the equation, so you can apply this to any function rule problem for any value of x.
Where is says 16+6 the answer is 22 not 32. The box that is unfilled is 8.
Answer:
150.88 cm²
Step-by-step explanation:
From the figure above;
- We are given the dimensions of a rectangular prism;
- we need to determine the total surface area;
From the figure you realize, there are three pairs of similar rectangles;
Thus; since area of a rectangle is L × W
Then;
First pair;
Area = 7.4 cm × 3.1 cm × 2
= 45.88 cm²
Second pair;
Area = 5 cm × 3.1 cm × 2
= 31 cm²
Third pair;
Area = 5 cm × 7.4 cm × 2
= 74 cm²
Therefore;
The total surface area = 45.88 cm² + 31 cm² + 74 cm²
= 150.88 cm²
Thus, the total surface area of the rectangular prism is 150.88 cm²
Answer:
1 to 2.333
Step-by-step explanation:
3/3=1 7/3=2.333 . . .
So I think its (1:2.33) or 1 to 2.33
