Answer:
121
Step-by-step explanation:
A calculator can answer this for you.
_____
Following the steps of the <em>order of operations</em>, you evaluate inner parentheses first. The exponents are the first to be evaluated there.
11[6^2/(5^2-4^2)+7]
= 11[6^2/(25 -16)+7]
= 11[6^2/9 +7]
Then you do the exponent ...
= 11[36/9 +7]
Now you do the division ...
= 11[4 +7]
And finally, you can finish up the outer parentheses ...
= 11·11
= 121
Answer:
10
Step-by-step explanation:
When we simplify we get
Then we continue to factor to get: 
We then see that we can factor
into
we then do the prime factorization of 847, which i think is,
. we have to find the numbers that multiply to 847 and then plug them into z+5, 3x=1,2y+7.
It has to be a positive, non-negative integer, right?
We also see that 3x+1=11 so we see that x=10/3 (which wont work).
So 3x+1=7, so x=2.
So 11 has to be in another term. It has to be in 2y+7=11 so y=2
for the last term we get z+5=11 so z=6
2+2+6=10
Hope this helps and if you want please consider giving me brainliest. :)
Answer:
B) 176 ft²
Step-by-step explanation:
First Photo - This is the problem drawn into the paper. If you have two vectors and they form a right angle (90°) between them, the Resultant Vector will appear like this, from the right angle.
Obs.:
1 - VR = Resultant Vector;
2 - The angle formed by the VR and the two vectors ISN'T a bisector.
Second Photo - You can move the bottom extremity of the Y vector to the arrow of the X vector and the tips from the Y and VR vectors will meet, forming a Right Triangle, whose the VR is the Hypotenuse (Opposes the right angle / Larger Side).
Now you just put the values in the Pythagorean Theorem:

Where VR is the "a".
