T+7/5=-4
Isolate the variable
T+7/5=-4
-7/5 -7/5
T=-4 -7/5
make both numbers with the same denominator on the right side
T= -20/5-7/5
solve
T=-27/5
(f+g)(7)=f(7)+g(7)
Step-by-step explanation:
A) f(7)=7²=49 and g(7)=√5=~2,2 and 49+2,2=51,2
B) f(7)/g(7)=49/2,2= 22,2
A <span>dodecagon has 12 sides
Sum of the interior angles = (12 - 2) x 180 = 1800</span>°
One interior angle = 1800 ÷ 12 = 150°

Answer:
1.001 x 10^-8
Step-by-step explanation:
Answer:
Area = (5x² + 10x)unit²
perimeter = (12x + 4)unit
Step-by-step explanation:
A rectangle has a height of 5x and a width of x+2
A rectangle is a quadrilateral that is a four sided polygon with two opposite sides parallel and equal.
Area of rectangle = length x breadth
Or
= height × width
Area = 5x × x+2
Area = 5x(x + 2)
Area = (5x² + 10x)unit²
b) perimeter of rectangle = addition of all sides
= 2( length + breadth)
Perimeter = 2 ( 5x + x + 2)
= 2(6x + 2)
Open bracket
perimeter = (12x + 4)unit
