Answer:

So it gives you a little picture and tells you what would the question be if you had this graph.

Step-by-step explanation:

The correct answer would be B, find the area because the 4x + 3 is your length and 3x is your length, A = length * width. So the answer is B, find the area.

Answer:

Step-by-step explanation:

A) Length = 4x +3

Width = 3x

Perimeter = 2*(length + width )

= 2*(4x + 3 + 3x) {Add the like terms}

= 2*(7x + 3)

= 2*7x + 2*3

= 14x + 6

B) Area = length * width

= (4x + 3) * 3x

= 4x *3x + 3*3x

= 12x² + 9x

C) x = 8

Perimeter = 14x + 6 = 14*8 + 6 =112 +6 = 118 units

Area = 12x² + 9x = 12*(8)² + 9*8

= 12*64 + 72

= 768 + 72

= 840 square units

Sketch the following to help answer the question. Kite QRST has a short diagonal of QS and a long diagonal of RT. The diagonals

Natalija [7]

The two diagonals intersects at right-angle for a kite

the long diagonal also bisects the short diagonal so QP = PS = QS/2 = 6/2 = 3

QPR is a right-angle triangle with QR at 5 and QR at 3

RP = sqrt (5^2 - 3^) = 4m
