Answer: x=-2 y=13
2(-2)+1=-3 check
-2-2=-4 check
Step-by-step explanation:
Horner's method:
2 1 -3
1 -2 -4
delta = det(
2 1
1 -2) = 2×-2 - 1 = -5
x = det(
-3 1
-4 -2)/-5 = (-2×-3-1×-4)/-5 = -2
y = det(
2 -3
1 -4)/-5 = (-8+3)/-5 = 1
Or by elimination
x = 2y - 4 from adding 2y=2y to second eqn
2(2y-4)+y=-3 by substituting for x in first.
4y-8+y=-3
5y=8-3=5
y=1
x=2y-4=2-4=-2
It's a degree, however in algebra there are also radians and gradians
Answer:
Surface area of the triangular prism = 186.984 feet²
Step-by-step explanation:
Surface area of the triangular prism is given by the expression,
Surface area = (Perimeter of the triangular base)×Height + Area of the triangular bases
Perimeter of the triangular base = (9.8 + 8.5 + 6.2)
= 24.5 ft
Height of the prism = 5.5 ft
Area of the triangular base =
=
= 26.117 square feet
Surface area of the prism = (24.5 × 5.5) + (26.117 × 2)
= 134.75 + 52.234
= 186.984 square feet
