Answer:
A=54m²
Step-by-step explanation:
A = hbb/2 =9 · 12/2 = 54m²
<u>Finding the constant of proportionality</u> :
<u>Finding y when x = 6</u> :
- y = 10(6)²
- y = 10(36)
- y = 360
The value of y is <u>360</u> when x = 6.
Green is 4 and Purple is 6 so you put it in a fraction by adding all of them and the just green and purple so 10/30 simplified is 1/3.
The answer is b
The perimeter of a rectangle is 2(l + w) so in this case, it is 2(15 + 9) and that is equal to 48. But so at c and d. So u need to multiply the width by 2 (9*2=18) and then you’ll see that 18-3=15. And therefore, the length is -5 and the width is 9
