Answer:
ok so differnce of 2 perfect ssquares are
x^2-y^2=(x-y)(x+y)
we are given
one factor is 5x-8
remember that all you do is square both terms individually to get them
(5x)^2=25x^2
8^2=64
they are difference so
25x^2-64 is answer
Holly is thinking of a number.
3/4 of Holly's number is 39.
Work out the number Holly is thinking of.
Answer:
52
Step-by-step explanation:
To find the number multiply 39 by the reciprocal of [tex]\frac{3}{4}[/tex], that is [tex]\frac{4}{3}[/tex]
number = [tex]\frac{4}{3}[/tex] × 39 = 4 × 13 = 52
Answer:
52.
Step-by-step explanation:
Take the number Holly's thinking as '[tex]x[/tex]'.
[tex]\frac{3}{4}[/tex] of [tex]x[/tex] is 39
[tex]\frac{3}{4}[/tex] x [tex]x[/tex] = 39
3[tex]x[/tex] = 39 x 4
3[tex]x[/tex] = 156
[tex]x[/tex] = [tex]\frac{156}{3}[/tex]
[tex]x[/tex] = 52.
The number Holly thought of was '52'.

1 If y = 0, which of the following is equivalent to the expression below?
15yº
5y3
• (A) 3y?
• (B) 3y6
• (C) 10y?
• (D) 10y6
Answer:
we have
15yº=15*1=15
when
y=0
5y³=5×0³=0
I think question was wrong it may be
[tex] \frac{15 {y}^{0} }{5 {y}^{3} } [/tex]
=[tex]3 {y}^{ - 3} [/tex]

True or False The sum of the squares of the lengths of the legs of an isosceles triangle is equal to the square of the length of the hypotenuse
Answer: False
Step-by-step explanation:
If the square of the length of the longest side of a triangle is less than the sum of the squares of the lengths of the other two sides, then the triangle is an acute triangle.
How do i do A for this part of flower bed area

Can you find the
rectangle's perimeter
I’m marking branliest
Answer:
8x + 4
Step-by-step explanation:
Perimeter = 4x - 3 + 4x - 3 + 5 + 5 =
8x - 6 + 10
= 8x + 4
Hope that helps! :)
-Aphrodite
Answer:
P = 8x+4
Step-by-step explanation:
To find the perimeter of a rectangle
P = 2(l+w) where l is the length and w is the width
P = 2( 4x-3+5)
Combine like terms
P = 2(4x+2)
Multiply
P = 8x+4

Tania has a set of nesting rings. This table shows the relationship between the radius of a ring and the ring's circumference.
What is the circumference for the nesting ring with a 9.5 cm radius?
Answer:
59.66 cm
Step-by-step explanation:
Circumference of a circle = 2πr
π = 3.14
r = radius = 9.5
2 x 3.14 x 9.5 = 59.66 cm

Which line is parallel to the line Y = X +7?
A. X-y=5
B. X+y=-2
C. Y=1
D. X=1
Answer:
a
Step-by-step explanation:
y=1 has a slope of 0,
x=1 has an indefinite slope,
x+y has a negative slope, so
x-y would be the only oneeft

What is the measure of angle "A"?
Answer:
[tex]<A=106[/tex]
Step-by-step explanation:
The given figure is an isosceles trapezoid, this means that the two non-parallel sides in the trapezoid are congruent. One of the properties of an isosceles triangle is that opposite angles are supplementary. This means that the sum of angles opposite each other in an isosceles trapezoid is (180) degrees. One can apply this here by stating the following,
[tex]<A+<C=180[/tex]
Substitute,
[tex]<A+74=180[/tex]
Inverse operations.
[tex]<A=106[/tex]

If length of petal is given in graph, that gives a value.
n value is from number of petals
Step-by-step explanation:
hope this helps :D
(btw I hate rose graphs...)
Answer:
Rose curve equations have two forms: r = a cos(nθ) and r = a sin(nθ) where a ≠ 0 and n is a positive integer. Petals have length determined by a. If n is odd, the number of petals is n. However, if n is even, the number of petals is 2n.

Which equation matches to the graph?
1. y = -x + 1/2
2. y = (-1/2)x - 1
3. y = 2x - 1
4. y = 4x + 2
Answer:
2. y = -1/2x - 1
Step-by-step explanation:
First we want to find the slope of the line.
To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values using two points (-4, 1) & (2, -2)
(-2 - 1) / (2 - (-4))
Simplify the parentheses.
= (-2 - 1) / (2 + 4)
= (-3) / (6)
Simplify the fraction.
-3/6
= -1/2
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = -1/2x + b
b is the y-intercept when the line crosses the y-axis.
From the graph, we can see that the point on the y-axis is (0, -1)
Therefore, b is -1.
Plug this into the equation.
y = -1/2x - 1
Hope this helps!
Answer:
Points :-
( -2,0)(0,-1)Calculation of Slope :-
m = 0+1/-2-0m = 1/-2m = -1Y intercept :-
y intercept = -1Using Slope Intercept Form :-
y = mx + c y = -1/2x + -1
