The area of a trapezoid is (a+b)/2 * h
a is the length of the small base which is the one on the top and is 4cm
b is the length of the big base which is the one at the bottom and is 4 + 3 + 3 = 10cm
h is the height which is 7cm
So the area is (4+10)/2 * 7
A= 14/2 * 7
A= 7 * 7
A= 49 cm^2
Answer:
2.
3.
Step-by-step explanation:
<em>In general we can write a polynomial in standard form as </em>
<em>Given</em>
<em>Combine the like terms: 4m and -4m</em>
<em>4m-4m=0</em>
<em>We have 4m-4m=0</em>
<em>So, write the remaining terms</em>
=
<em>This is in decreasing order of powers.</em>
<em>Hence the answer is the standard form is</em>
<em>But in the given options, you can choose option 2 and option 3 are in standard form.</em>
<em>Because they are in decreasing order of powers.</em>
<em>In other two options, the constants term is first and the highest power term is at the last. So, they are not in standard form.</em>
<em>-2m^4-6m^2+4m+9</em>
<em>-2m^4-6m^2-4m+9</em>

Answer:
l = 24ft
Step-by-step explanation:
A = lw
360 = (x + 9)(x)
360 = x^2 + 9x
0 = x^2 + 9x - 360
0 = (x + 24)(x - 15)
x ≠ -24 (length cannot be negative)
x = 15
l = 15 + 9
l = 24ft
72cm
you multiply the outside length (6cm each) by how many there are
Answer:
40.56
Step-by-step explanation:
you need the circumference of the cirle aka perimeter of circle so 8(pi) and then because its only half, divided by 2... 12.56
now you hgave circumference so add 12.56 to 28 and there you go. you can round how ever necessary
