Answer:
y²+4y
Step-by-step explanation:
y multiplies with (y+4)
y times y is y²
y times 4 is 4y
That leaves you with y²+4y
Answer: expresses the area.
Let the width of a rectangle be 'y' feet.
Let the length of a rectangle be 'y+4' feet.
As we know the area of rectangle :
Area of rectangle is given by
Hence, expresses the area.
a) 300m
b) 15 miles
a) 1 : 30 000
= 1x 30 000
= 30 000cm
= 30 000cm/ 100 Representing in metres
= 300m
b) 1 : 6
= 1x 2.5 : 6x 2.5
= 2.5 : 15
= 15 miles
y = (5x – 9) ÷ (–4)
3 − 4y = 5x − 6
–3 –3–4y = 5x – 9
÷(–4) ÷(–4)
5(x+10)=25
5x+50=25
5×0+50-25=0
0+25
