Answer:
15cm2
Step-by-step explanation:
Area of rectangle = l×b
l=5cm, b=3cm
Area= 5×3 =15cm2
K= 8. If you look at the pattern each x value is multiplied by 8 to give you the y value. You could also solve it by:
40=k5
40/5=k
8=k
you could do this with any of the x or y values and still end up with 8.
“10 more that” means “add 10 to something”
“twice” means “multiply something by 2”
Use “x” or another variable for “a number”
Twice a number: 2*x or 2x
10 more than twice a number: add 10 to 2x
Answer: 2x+10
Answer: 226.5 ft²
<u>Step-by-step explanation:</u>
I divided the image into 3 rectangles and 1 triangle.
top rectangle: length = 9, height = 4 --> A = 9 x 4 = 36
middle rectangle: length = 15, height = 7 --> A = 15 x 7 = 105
bottom rectangle: length = 18, height = 4 --> A = 18 x 4 = 72
triangle: base = 9, height = 3 --> A = (9 x 3)/2 = <u> 13.5 </u>
<u>Total </u> = 226.5
