Answer:
20,000m²
Step-by-step explanation:
If they jog 12 km/h for half an hour, they have covered.
12 X 0.5 = 6km in 10 circuits. Making 1 perimeter
6 / 10 =0.6 km (600 m).
To determine area we need to convert this perimeter to length and width. We know that it is a rectangle, with 2 equal widths and 2 equal lengths, and the length is twice the width.
So L = 2W
Perimeter = 2W + 2L
600 m = 2W + 2(2W)
600 m = 6W
W = 100 m
L = 200 m
Area = 100 X 200 = 20,000 m²
9x + 2 + 8x + 1 = 17x + 3
The answer is 180 - 17x + 3 I'm pretty sure
Answer:
Step-by-step explanation:
The scale factor, or linear scale factor, is the ratio of two corresponding side lengths of similar figures. Similar figures have the same shape but are different sizes. The scale factor is used to solve geometric problems. You can use the scale factor to find the missing side lengths of a figure.
Answer:
The mistake is in step 1 when you do -2(x+4) you do the distributive property first -2 times x is -2x that's correct but -2 times 4 is not 8 it is -8
when you multiply by negatives the answer will always be a negative unless your multiply 2 negative number together then itll be positive ex. 4 × -4 = -16 (negative) but -4 × -4 = 16 (positive)
