Which is true about the expressions?
The expressions are equivalent because Ella got different results when she substituted zero for f.
The expressions are equivalent because Ella got the same result when she substituted zero for f.
The expressions are not equivalent because Ella would get different results when substituting different numbers for f.
The expressions are not equivalent because Ella would get the same results when substituting different numbers for f.
Answers
Answer *The expressions are not equivalent because Ella would get different results when substituting different numbers for f.
（But I'm not sure.
Answer:
the answer is b
Step-by-step explanation:
bcz when she substituted 0 for f she got the same result on both the answers
it does matter what the constant of the first term is as long as the second term remains the same ( the first constant or number is being multiplied by 0 the result will always be 0)

If a square has a perimeter of 36cm how long is each side of the square
Answers
Answer:
9 cm
Step-by-step explanation:
→ Remember how many sides a square has
4
→ Divide it by the perimeter
36 ÷ 4 = 9
Step-by-step explanation:
you know what a square is ?
it is a closed shape with 4 sides.
all 4 sides are equally long.
all 4 inner angle are 90 degrees.
you know what a perimeter is ?
it is the circumference, the whole way one time around the shape, around the outline of a given structure.
if you don't know the terms, for heaven's sake, please ask your teacher, your friends, your parents or us here directly.
don't wait. don't be afraid or ashamed.
because this here is an extremely simple problem to solve, once you understand the words used.
so, as per the explanations, the perimeter of a square is the sum of the lengths of all sides. and because all sides are equally long, this means the perimeter is simply 4 times the length of one side.
36 = 4×side
side = 36/4 = 9cm
so, each side of the square is 9cm long.

ReWrite 2/3 and 3/4 with a common denominator
Answers
Answer:
8/12 and 9/12
Step-by-step explanation:
2/3 = 8/12 and 3/4 = 9/12
To get two fractions with common denominators you can find the least common multiple of the denominators or you can multiply 2/3 x 4 and 3/4 x 3
The lowest common denominator between 4 and 3 is 12
To get from 4 to twelve we multiplied by 3. Whatever you do to the bottom you do to the top. The top number is 3.
3 x 3 = 9
So your new fraction is 9/12. If you simply this you get 3/4 so this checks out ✔️
Now we need to do the other fraction
To get to from 3 to twelve we multiply by 4
3 x 4 = 12
Whatever you do to the bottom you have to do it the same to the top
2 x 4 = 8
Now you get 8/12. 8/12 simplified is 2/3 so this Plato’s checks out ✔️
7. The ratio of the base to height of a triangle is 3:5. If the area of this triangle is 30, find the lengths of the base and height.
Answers
Answer:
Base= 6
Height= 10
Step-by-step explanation:
Area of triangle= ½ ×base ×height
Let the base be 3x and the height be 5x.
Given that the area is 30,
½ ×base ×height= 30
½(3x)(5x)= 30
Multiply both sides by 2:
3x(5x)= 60
15x²= 60
x²= 60 ÷15
x²= 4
Square root both sides:
[tex]x = \sqrt{4} [/tex]
x= 2
(reject x= -2 since length has a positive value)
Length of base
= 3x
= 3(2)
= 6
Length of height
= 5x
= 5(2)
= 10

Write the equation of the line, given the y and x-intercepts. a x-intercept = –68, y-intercept = –34
Answers
Answer:
In slope-intercept form, y = -17/34 - 34
Step-by-step explanation:
For the two points, you have (-68, 0) and (0, -34). To get the slope, you take (y-y) / (x-x). Stay consistent on the order you do those. After I did (-34 - 0) / (0 - 68), simplified it, and got a slope of -17 / 34. You are already given the y-intercept, so you just write the equation from there (y = -17/34 - 34)

The equation
(p-1)x^2 + 4x + (p-5)=0, where p is a constant,
has no real roots.
(a) Show that p satisfies p^2 - 6p+1>0.
Answers
Answer:
Proof is shown below.
Step-by-step explanation:
Use quadratic Formula, where from the standard form ax^2 + bx + c = 0, where a is not zero, we identify a = p-1, b=4, c = p-5, and since the given equation has no real roots, the discriminant b^2 - 4ac < 0, so that substituting we have that,
4^2 - 4(p-1)(p-5) < 0
16 - 4(p^2 - 6p + 5) < 0
16 - 4p^2 +24p - 20 < 0
-4p^2 + 24p - 4 < 0,
p^2 - 6p + 1 > 0, by dividing both sides of the inequality by -4.
