I found 1 and 2. x equals -11 and h=-3.85.
Answer:
2400 cm^2
Step-by-step explanation:
The surface area for a cube is just 6* area in one face (As there are 6 faces), so 6*20^2 = 6*20*20 = 2400 cm^2
10)
6y - 16 = 4y + 6
2y = 22
y = 11
11)
2x + 5x + 5 = 180
7x + 5 = 180
7x = 175
x = 25
Answer: The 6 sections has an area of 1/72 square yards
Step-by-step explanation:
Length= area / length
Length = 1/12 ÷ 1/3 = 1/12 × 3/1 = 1/4 yards
Since the width and length are different and the 6 squares must be arranged in a 2 × 3 pattern.
The long side is 1/3 yard
1/4 ÷ 2/1 = 1/4 × 1/2 = 1/8 yard
And the width is 1/3 ÷ 3/1 = 1/3 × 1/3 = 1/9 yard
The 6 sections are 1/8 × 1/9 and each one has an area of 1/8×1/9 = 1/72 square yard
Answer and Explanation
<h2>0</h2>
<em>This is because they are both the same opposite number, and you are adding.</em>
But, if it was,
then it would be
or
.
<em>So, the answer is 0.</em>
