Answer:</h3>
- The Surface area of milk can is 43.96cm²
<h3>Solution:</h3>
The milk can is in the shape of a cylinder.
The surface area of cylinder is defined as the sum of curved surface and the two circular bases of the cylinder;
ㅤㅤㅤ➙ (curved surface ) + 2(base area )
ㅤㅤㅤ➙ 2πrh + 2πr²
ㅤㅤㅤ➙ 2πr( h + r )
<em>Here, in this question we have;</em>
- radius ( r ) = 2/2 = 1 cm
<u>Therefore, </u><u>Surface</u><u> </u><u>Area</u><u> </u><u>(</u><u> </u><u>S.A </u><u>)</u><u> :</u>
➝ S.A = 2πr( r + h )
➝ S.A = 2 × π × 1 ( 1 + 6 )
➝ S.A = 2π ( 7 )
➝ S.A = 2 × 3.14 × 7
➝ S.A = 14 × 3.14
➝ S.A = 43.96cm²
Answer: In step 1, he should have added .75x to both sides.
-5x⁽²⁺³ˣ) - 2x(x-4)
Let's seperate the equation, and do the first half first.
-5x ⁽²⁺³ˣ⁾
Multiply -5x with 2.
Then, multiply 3x with -5x.
That gives us: -10x - 15x²
Now, let's do the second half.
2x(x-4)
2x²-8x
Now, let's put them together.
(-10x-15x²) - (2x²-8x)
Add like terms.
(-2x² - 15x²) - (-8x - 10x)
Simplify.
-17x² - (-18x)
-17x² + 18x

Answer:
47x (square units)
Step-by-step explanation:
The given shape is made up of:
<u>Area of the rectangle</u>
= width × length
= 3x × 14
= 42x
<u>Area of the triangle</u>
= 1/2 × base × height
= 1/2 × (14 - 9) × (5x - 3x)
= 1/2 × 5 × 2x
= 5x
<u>Area of given shape</u>
= area of rectangle + area of triangle
= 42x + 5x
= 47x (square units)
The answer is D.
6 wasnt multiplied by 3.
the expression should look like this "6m+18"
