The base of the triangle is x² + 2x + 4
The height of the triangle is 2x² + 2x + 6
The area of the triangle is
A = (1/2) b h
Substituting
A = (1/2)(x² + 2x + 4)(2x² + 2x + 6)
Which can be expanded or factored
Answer:x=4
7.5x=30
Divide by 7.5 on both sides
x+4
Answer:
36%
Step-by-step explanation:
change÷original amount x100
480÷100= 4.8 = 1%
173÷4.8= 36%
Answer: Option 'C' is correct.
Step-by-step explanation:
Since we have given that
An arc is a part of total circumference of circle and length of that arc is the measurement of linear distance.
Since we know the formula for "Length of an arc " , we get
Hence, Option 'C' is correct.
To evaluate the radius of the cone we proceed as follows:
V=1/3 πr²h
plugging in the values, v=88π, h=8 ft
step 1
88π1/3πr²(8)
step 2
88π=8/3πr²
step 3
divide both sides by π
88=8/3r²
multiply both sides by 3/(8)
88(3/8)=r²
step 4
simplify
33=r²
step 5
get the square root
r=√33
Thus the mistake that Fatima made was:
<span> In step 3, Fatima did not multiply 88 by the reciprocal of 8/3 </span>
