Let the breadth be x m.
So, length = 4x m.
Area of the rectangle = 1936m sq.
So,
4x × x = 1936
4x^2 = 1936
x^2 = 1936/4
x^2 = 484
x = √484
x = √22×22
x = 22
Hence, breadth = 22m.
Length = (4×22)m = 88m.
Answer:
T + V = 50
2T + (3/2) * V = 90
2T + 1.5V = 90
T = 50 * 1.5 - 90 * 1 / 1 * 1.5 - 2*1 = 30
V = 1 * 90 - 2 * 50 / 1 * 1.5 - 2 * 1 = 20
Step-by-step explanation:
T = 30
V = 20
Answer:
He could use y+3x=-4
Step-by-step explanation:
When we subtract 3x on both sides, we get y=-4-3x, which means we just solved a variable and can substitute into the other equation 2x-3y=-21
Answer:
D
-3 * (-4) matches, as well as the powers (I guess you wanted to communicate that these are powers, but it would also be correct if these where factors)
