8x+4 = 4(2x+1) Take out the common factor 4
Recall the Pythagorean identity,
So we have
But squaring any real number always gives a non-negative number, so there are no real solutions to this equation.
Area should be 51? (base times height and I divided the shape into two different shapes then added together) and I get 43 for the perimeter...I’m not certain in the perimeter is correct though so I apologize if it is incorrect. I can’t remember if you count the actual bordering red squares or if you only count the while squares AROUND the red squares....
Answer:
117
Step-by-step explanation:
Okay, the problem is asking that we find the hypotenuse of this triangle (AKA, the lake.)
a²+b²=c²
A= 75
B= 90
C is always the hypotenuse.
75²+90²= c²
5,625+8,100= 13,725
√13,725= 117.15374513859981591194584103639
To the nearest whole number: 117
To the nearest tenth: 117.2
Hope this helps!
