Answer:

105 $cm^{2}$

Step-by-step explanation:

Rectangle 2 is 3 times rectangle 1. We know this because one side of rectangle 2 is 3 times the same side of rectangle 1.
Area of rectangle 1 × 3 = area of rectangle 2: 35 × 3 = 105 $cm^{2}$

I hope this helps!

Two numbers have these properties:

Elina [12.6K]

The two numbers are 12 and 30

Step-by-step explanation:

Let us revise the meaning of HCF (highest common factor) and LCM (least common multiple)

The highest common factor of two numbers is the largest whole number which is a factor of both, the HCF of 4 and 6 is 2 because the factors of 4 are 1, 2, 4 and the factors of 6 are 1, 2, 3, 6; the common factors are 1, 2 and the greatest is 2 so the highest common factor of 4 , 6 is 2
The least common multiple of two numbers is the smallest number that they both divide evenly into, the least common multiple of 4 and 6 is 12 because the multiples of 4 are 4, 8, 12, 16, ... and the multiples of 6 are 6, 12, 18, 24, ...; the first common multiple between then is 12

∵ Both numbers are greater than 6

∵ Their HCF is 6

- That means 6 is a factor of both of them

∴ The two numbers are multiple of 6 without any other common

factor greater than 6

Let us write the multiple of 6 greater than 6

∵ 12 , 18 , 24 , 30 , 36 , ......... are multiples of 6

∵ Their LCM is 60

- That means 60 can divided by them

∵ 60 can divided by 12

∵ 60 can divided by 30

∵ The factors of 12 are 1 , 2 , 3 , 4 , 6 , 12

∵ The factor of 30 are 1 , 2 , 3 , 5 , 6 , 10 , 15 , 30

∵ Their common factors are 1 , 2 , 3 , 6 and the greatest one is 6

- 12 and 30 have HCF of 6 and LCM of 60

∴ The two numbers are 12 and 30

The two numbers are 12 and 30

Write an equation for the line in point-slope form.Passing through (5,3) with x-intercept 6

Rama09 [41]

Remember that the point-slope form of a line is:

$y-k=m(x-h)$

For a line with slope m and that passes through point (h,k)

Now, let's work on the line we're given. SInce the x-intercept is 6, we know that the line passes through (6,0).

Let's calculate the slope m :

$m=\frac{3-0}{5-6}\rightarrow m=\frac{3}{-1}\Rightarrow m=-3$

Now, using point (5,3) we can get the following point-slope form for the line:

$y-3=-3(x-5)$

PLEASE HELP

Zinaida [17]

We want to identify different things on the given graph.

The solutions are:

A) (3, -1)

B) x = 4

C) x = y^2 + 2y + 4

D) x ⇒ ∞, y ⇒ ∞

x⇒3, y⇒ -1

A) The first thing we want to identify is the vertex, we could say that a vertex is a point of symmetry. (like the minimum/maximum of a parabola). Here we clearly do not have a point of symmetry, as we only have half of a parabola, but if it was a complete one, the vertex would be at the blue point, in (3, -1)

B) This is the point where the graph intercepts the x-axis, x = 4.

C) we want to write the equation, we start with the general parabola, this time as a function of y:

x = a*y^2 + b*y + c

Remember that the x-itercept is at x = 4. then c = 4.

x = a*y^2 + b*y + 4

The y-value of the vertex is -1, while the general y-value of the vertex is:

y = -b/2a = -1

And evaluating the equation in this value, gives us:

x = a*(-1)^2 + b*-1 + 4 = 3

Then we have two equations:

-b/2a = -1

a + -b + 4 = 3

We can rewrite the first one as:

-b = -2a

b = 2a

Now we can replace this on the other equation:

a - 2a + 4 =3

-a + 4 = 3

-a = 3 - 4 = -1

a = 1

And b = 2a = 2*1 = 2

Then the equation of the parabola is:

x = y^2 + 2y + 4

D) We can see that as x grows, y increases, so we can say that:

x ⇒ ∞, y ⇒ ∞

And for the other limit we can see that as x tends to 3, y tends to -1, then:

x⇒3, y⇒ -1

A figure is dilated by a

Reptile [31]

Answer: 1.5x

Step-by-step explanation:

If the figure dilates by 1.5 times it will increasingly do the same with the perimeter. It keeps the same ratio of 1.5x.

Ex: If a side of the figure was originally 10 and the dilation factor is 1.5 the side now with be 15. This goes for all sides.

Hope this helps!
