For this you do Pythagorean theorem so
7^2+12^2=x^2
49+144=x^2
193=x^2
x=squareroot193
so you put 193 in the green box.
hope this helped❤️
Answer:
y=1343
Step-by-step explanation:
when you plug in 21 for x the equation would be 3(21)^2+20 solve using the order of operations and you get 1343
The LCM of two given numbers will be greater. For example, a factor is the two numbers multiplied together to get that certain m=number that you chose, which is usually pretty less, than the LCM is the multiple of those certain numbers, and if you put those together the answer to the factors (multiples) are most larger than the factors itself.
Answer is a= -5
Reason
Distribute multiply parentheses first
-3(a-8) +4a= -8(a+3)+3
-3a +24 +4a = -8a -24 +3
Now combine like terms to isolate “a”
-3a +4a +8a = -24 +3 -24
9a = -45
Now divide both sides by 9 to solve for “a”
a= -5
This would be the same as the square root of 16. So the answer is 4!
