<h2>Answer:</h2>
[1] Area of base = 13 × 13 = 169in².
Area of faces = 4 (1/2 × 13 × 8) = 208in².
Surface area = (169 + 208)in² = 377in².
[2] Area of base = 1/2 × 5.2 × 4.5 = 11.7in².
Area of faces = 3 (√3/4 × 5.2²) = 35.1in².
Surface area = (35.1 + 11.7)in² = 46.8in².
[3] Area of base = 7 × 10 = 70in².
Area of faces = 2(1/2 × 7 × 6) + 2(1/2 × 10 × 4.8)
= 98in².
Surface area = (70 + 98)in² = 168in².
Answer:
x > 5
Step-by-step explanation:
Formula: length x width
First, you must substitute in the numbers.
16-2x*10 < 60
Work:
(16-2x)10 < 60
Then, distribute the 10 to the 16 and to the 2x.
160-20x < 60
Next, substract 160 from both sides.
-20x < -100
Now, divide -20 from both sides.
x < 5
This isn't the answer yet because you have to flip the sign because you divided by a negative.
x > 5
Answer: 6 inches
Step-by-step explanation:
If rectangle 2 is 3 times as long as rectangle 1, then all we hae to do is divide the width by 3 (The width is 18)
18 ÷ 3 = 6
3 and 17 that’s all there is to it, prime numbers are numbers that don’t divide by anything but itself and one
