Answer:
(x+4)(x+4)
Step-by-step explanation:
The middle number is 8 and the last number is 16. Factoring means we want something like (x+_)(x+_). We need two numbers that add together to get 8 and multiply together to get 16. The number 4 works perfectly in this equation. That's why (x+4)(x+4) is the factor of the equation x^2 + 8x + 16.
Answer:
11. Volume = 2181.2mm^3
12. Surface Area = 1204.49mm^2
Step-by-step explanation:
We first need to find the hypotenuse side of the triangle using the Pythagorean theorem:
a^2+b^2 = c^2
13.3^2+20.5^2 = c^2
176.89+420.25 = c^2
597.14 = c^2
24.44 = c
Now we can find the volume using the formula:
V = 1/4(16)sqrt-13.3^4+2(13.3*20.5)^2+2(13.3*24.44)^2
-20.5^4+2(20.5*24.44)^2-24.44^4
V = 2181.2mm^3
To find the surface area using the surface area formula:
A = (13.3*16)+(20.5*16)+(24.44*16)+1/2sqrt
13.3^4+2(13.3*20.5)^2+2(13.3*24.44)^2
-20.5^4+2(20.5*24.44)^2-24.44^4
A = 1204.49mm^2
answer.
It will be 750 units
Step-by-step explanation:
we multiply the ten by sevety five and the answer is 750
