Answer:
false
Step-by-step explanation:
1.2 squared is 1.44 and 0.5 squared is 0.25, if you add those together you get 1.69 which does not equal 1.3 so its false, hope this helps!
Answer:
(x+1)(x-14)(x+3)
Step-by-step explanation:
The first step in factorising polynomials is to find the smallest factor first. The way to do this is with trial and error. Lets see if x+1 is a factor.
According to the factor theorem, (x-a) is a factor of P(x) if and only when P(a) = 0
In this case we will use f(x) = ((x)^3)-((10x)^2)-53x-42
f(-1) = 0
Therefore (x+1) is a factor of the polynomial.
Now we divide the polynomial with (x+1) via long division to get (x^2)-11x-42.
We now factorise (x^2)-11x-42 using whatever method you would like. I'm going to use the AC method, where we find a number that multiplies to AC and adds to B, In this case AC = -42, and B = -11.
Therefore (x^2)-11x-42 factosied is (x-14)(x+3)
Now merge (x+1) with (x-14)(x+3)
The final answer is (x+1)(x-14)(x+3)

To find how much larger Greenland is you would have to subtract the New Guniea square miles ( 306,000 ) from the Greenland square miles ( 840,000 ) ; 840,000 - 306,000 = 534, 000 , so " 534,000 " is the correct answer.
E should be Youre answer I’m pretty sure
Answer:
a = 26
Step-by-step explanation:
Solve for a:
22 = a - 4
Hint: | Reverse the equality in 22 = a - 4 in order to isolate a to the left-hand side.
22 = a - 4 is equivalent to a - 4 = 22:
a - 4 = 22
Hint: | Isolate terms with a to the left-hand side.
Add 4 to both sides:
a + (4 - 4) = 4 + 22
Hint: | Look for the difference of two identical terms.
4 - 4 = 0:
a = 22 + 4
Hint: | Evaluate 22 + 4.
22 + 4 = 26:
Answer: a = 26
