Answer:
13- No because the size of the triangle can be different, meaning bigger side length
in 14 he is forgetting the lines at the angles. The little circular ones that say the angles are congruent.
Step-by-step explanation:
Area of a triangle = (b·h)/2
the base would be the diameter of the circle, so 4+4=8 ft, the height is 10 ft.
A= (4×10)/2
A=20 ft²
Answer:
B
Step-by-step explanation:
-5[ (x³+1)(x+4) ] = -5[ x³*(x+4) + 1*(x+4) ]
= -5 [ x³*x + x³*4 + 1*x + 1*4 ]
= -5 [ x⁴ + 4x³ + x + 4]
= -5*x⁴ + (-5)*4x³ + (-5)*x + (-5) * 4
= -5x⁴ - 20x³ - 5x - 20
The simplified answer is 4/5
Answer:
44%
Step-by-step explanation:
the area of a rectangle = Length × Breadth
original area of james pit = 20×20=400in²
new size = 20 + 4 =24 inches
new area = 24 × 24= 576in²
increase in area = 576 - 400 = 176
percentage increase = 
× 100
=
× 100
=0.44 × 100
=44%
percentage increase in area is 44%
