Answer:

Step-by-step explanation:
Be VERY careful. When it write out the equation that way, it will give the speculation of this:

Now, in this case, since you were extra explanatory about this [what is written in parentheses], two factors I know of that multiply to 15 are these:

Answer:
100
Step-by-step explanation:
because 5+5=10
the 10^2=10*10=100
Answer:
Step-by-step explanation:
Since you know the angle is a right angle, you can say that the two equations equal 90. A right angle is 90 degrees
3x+40+4x-6=90
Then Simplify
7x+34=90
Then Subtract:
7x=56
Then Divide:
x= 8
After, plug x into the angle equations
1. 3(8)+40= 64
2.4(8)-6= 26
The angles are 64 and 26
Answer:
Approximately 6.4
Step-by-step explanation:
We can use the pythagorean thereom here, that tells us (a^2)+(b^2)=c^2. C is the hypotenuse, the side opposite from the right angle, while a and b are the other sides. We can insert 5 and 4 as a and b, and solve for c
:(5^2)+(4^2)=c^2
:25+16=c^2
:41=c^2
:sqrt(41)=6.4=c (We square rooted both sides. 6.4 is only rounded to the nearest hundredths place.) Hope this helps!
