One solution ! Which is x=-3
Answer:
40 ft squared
Step-by-step explanation:
To calculate area of a rectangle, you use the formula length times width, or base times height.
5 x 8 = 40 feet squared
Answer:
6/21.
Step-by-step explanation:
let the rational number be 2x/7x.
2x + 4 / 7x - 2 = 10 /19
Cross multiply:
19(2x + 4) = 10(7x - 2)
38x + 76 = 70x - 20
96 = 70x - 38x
32x = 96
x = 3.
So the rational number is 2*3/ 7*3
= 6/21.
Answer:
Area = 31.5 units^2
Step-by-step explanation:
7 x 3 = 21
Area of triangle is (height x base) / 2
(3 x 7) / 2 = 10.5
21 + 10.5 = 31.5
