Answer:
R= 22537
Step-by-step explanation:
Answer:
450cm3 or 450 cube cm.
Step-by-step explanation:
Formula = Length x Width x Height
So,
5 x 7.5 x 12 = 450cm3
Answer:
There is no points of intersection
Step-by-step explanation:
∵ The slope of line u = 4 - (-8)/5 - 9 = 12/-4 = -3
∴ Its equation is ⇒ y = -3x + c ⇒ use point (5 , 4) to get c
4 = -3(5) + c ⇒ c = 4 + 15 = 19
∴ The equation of u is ⇒y = -3x + 19
∵ The slope of line v = -7 - 2/7 - 4 = -9/3 = -3
∴ Its equation is ⇒ y = -3x + c ⇒ use point (4 , 2) to get c
2 = -3(4) + c ⇒ c = 2 + 12 = 14
∴ The equation of v is ⇒y = -3x + 14
∵ The slopes of them are equal and their y-intercepted are not equal
∴ Line u is parallel to line v
∴ There is no point of intersection
This is a trapezoid cause has 2 lines paralel and 2 lines are not paralel.
Answer:
Lengths of the sides in the given order
15 inches
15 inches
30 inches
Step-by-step explanation:
The total of the sides,
(2x + 5) + (2x + 5) + (5x + 5)...then add the variables with x together and those without x together.
; 9x + 15
Hence if the perimetre of the triangle is 60 in
then...; 9x + 15 = 60
; 9x = 45
;Hence the variable.., x = 5
Lengths of the sides,
Substitute the value of x into the given lengths of the sides,
2(5) + 5 = 15 inches
2(5) + 5 = 15 inches
5(5) + 5 = 30 inches
