Answer:
x=4
Step-by-step explanation:
area of rectangle= length x width
4+5=9
4
9x4=36
Answer:
900.
Step-by-step explanation:
1) the initial area is: A₀=0.5*base*h;
2) the final area is: A=0.5*(5*base)*(5*h).
It means, that 25A₀=A, then A=900 [cm²].
Answer:
Hello! The answer will be below!

Angles that create a triangle always add up to 180.
To find sides that create triangles, we have to use the Triangle Inequality Theorem.
It's where side A + B will <em>always</em> be greater than side C
and B + C will always be greater than side A
<em>and</em> A + C will always be greater than side B.
So let's check all of these answers and pick the one that's incorrect.
A.
10 + 25 + 145 = 180?
Correct!
B.
9 + 15 > 9?
Correct!
15 + 9 > 9?
Correct!
9 + 9 > 15?
Correct!
C.
40 + 70 + 60 = 180?
Incorrect! 40 + 70 + 60 = 175 which is less than 180.
The answer is three angles measuring 40 m, 70 m, and 60 m.
