Answer:
first term of the pattern (T₁) : 10
Step-by-step explanation:
T₁ ; 1 ; -6 ; T₄ ; -14
1-T₁ ; -6-1 ; T₄-(-6) ; -14 -T₄ (First Tₙ-Tₙ₋₁)
-8+T₁ = T₄+13 = -2T₄-20 (2nd Tₙ-Tₙ₋₁ is constant)
T₄+13 = -2T₄-20 3T₄ = -33 T₄ = -11
-8+T₁ = T₄+13 -8 + T₁ = -11 + 13 = 2
T₁ = 10

Answer:
1.1995
2.114.4
3.270
Step-by-step explanation:
1. Multiply the length and width
2. Multiply 14.3*8
3. Multiply 15*36 and divide the product by 2
to find the area of a rectangle, multiplty length times width
for the area of a triangle, multiply the bottom of the triangle by the height and divide it by 2.
Answer:
Probably the first one because the other two questions would be un-reliable
Step-by-step explanation:
