Answer:
no solution
Step-by-step explanation:
7m-(5m-12)= 8+2m+4
2m+12= 2m+4

Step-by-step explanation:
the area of a triangle is baseline×height/2
in case of such a right-angled triangle we can use the sides that enclose the 90 degree angle as baseline and height.
so,
B = 8×6/2 = 8×3 = 24 yd²
the height h is 8 yd (as the picture clearly shows).
the perimeter of the base is the sum of all three sides
P = 8 + 6 + 10 = 24 yd
Answer:
y= 4x-7
Step-by-step explanation:
First, we need to find the slope. We can do this by using the formula:
1) y₂-y₁/x₂-x₁
2) 9-5/5-3
3) 4/2
4) The slope is 2
Next, we have to first plug the slope (2) and one of the coordinate pairs (I chose (3,5)) into point-slope format.
5) y-y₁=m(x-x₁)
6) y-5 =4(x-3)
7) Now we just simplify this equation to make it slope intercept form (y=mx+b)
8) y-5= 4x-12
9) y=4x-7
And there you have it :)
V + f = a + 2
15 + f = 24 + 2
f = 26 - 15
f = 11 (11 faces)
height = 43 m
d = 14m
r = 7 m
A = π.r.g
g² = r²+h²
g² = 7²+43²
g² = 1898
g = \/1898
g ~ 43,56 m
A = π.r.g
A = π.7.43,56
A = 304,92 π
A = 304,92*3,14
A = 957,45 m² (área lateral)
