the answer is 58
because to find the perimeter all you do is add all the sides together which is 12+15+8+9+14=58
i hope this helps you
first we have to find the slope Y2-Y1/ X2- X1
7-(-1)=8
5-(-4)=9 slope= 8/9
Poin slope form ------- Y-Y =M(X-X)
Y+7= 8/9 (X+5) or
Y-1= 8/9 (X-4)
Inclusive means including 1 and 80
ok so we know that 1^2=1 so 1 is a perfect square
just go up and square them untill 80 and the results is your answers
2^2=4, 4 is another
3^3=9
4^2=16
5^2=25
6^2=36
7^2=49
8^2=64
9^2=81 which is over
so the perfect squares from 1 to 80 are
1,4,9,16,25,36,49,64
The value a is 7.
<h3>What is Straight Line?</h3>
A line is simply an object in geometry that is characterized under zero width object that extends on both sides. A straight line is just a line with no curves.
Here, the given equation of line
y = ax -3
line passing through point (2, 11), then
11 = a X 2 - 3
11 + 3 = 2a
2a = 14
a = 7
Thus, the value a is 7.

Answer:
249.6
Step-by-step explanation:
width x height x 1/2 = area fo a triangle
12(2) x 10.4(2) x 1/2 = 249.6
I assumed this means all of the surface area. Hope this helps. Sorry if I'm wrong.
