Answer:
Perimeter=22 m
Step-by-step explanation:
Perimeter Of A Figure
Perimeter is the distance measured around a shape. If the figure is line-shaped, the perimeter can be obtained by adding the individual lengths of each segment around the shape.
The figure shown is surrounded by line segments. We only have to add them all to find the perimeter. But we don't need each individual length to do so. We may notice the following (given all angles are right):
The sum of HG+FE+DC equals AB. So the upper and lower lengths are twice AB, or equivalently: 2*7 1/2 m =15 m
It can also be noted that AH+GF=BC+DE=2 1/4+1 1/4 = 3 1/2 m. It means that the two lateral lengths are twice this value: 2* 3 1/2 = 7 m
Thus, the total perimeter is 15 m + 7 m = 22 m
we know that
the volume of the chip is 15.3 cm^3. the mass of the chip 14.3 grams
so
Step 1
Find the volume of a block of marble 30.0-by-40.0-by 100.0 cm
the volume is equal to
Step 2
Find the mass of a block of marble
by proportion
therefore
<u>the answer is</u>
The answer would be 7. The two minus signs cancel each other out and turn into a plus sign.
2x^2 • x^2 = 2x^4
First, multiply the terms with the same base by adding their exponents
2x^2+2
Then, add the numbers
2x^4
