solve for x and there is no need for an explanation!

21 + 18 = 39

147/39 = 3.7692307692307

3.7692307692307 x 18 = 67.846153846152, round to 67.80 and that's your answer

Answer:

16, Each side of the sqaure is 4 sq. units. 4+4+4+4=16 The area is also 16. 4x4=16

Step-by-step explanation:

The proof that shows that the quadrilateral is a square is from that fact that all of the sides have the same length.

The perimeter of the quadrilateral is given as

4+4+4+4 = 16

4L = 4X4 = 16

Hence it has being proven that the area and the perimeter of the shape is 16 hence this shape can be said to be a square.

Answer:

The correct answer is D) y = 2x - 5

To find the equation of the line, start by finding the slope. You can do this by using the slope formula below.

m(slope) = (y2 - y1)/(x2 - x1)

m = (1 - -3)/(3 - 1)

m = 4/2

m = 2

Now that we have the slope, we can use it along with either point in point-slope form to get the equation.

y - y1 = m(x - x1)

y - 1 = 2(x - 3)

y - 1 = 2x - 6

y = 2x - 5

Answer: y=2x-5

the points are 4 points away from each other vertically, and 2 away horizontally. This makes the slope 4/2 or just 2.

take the slope and go backwards until you hit the y axis and the y-intercept is -5

this means the equation is y=2x-5

Answer:

(C)  b = 0.

Step-by-step explanation:

Slope = (b - 5) / (3 - (-2)) = -1

(b - 5)/ 5 = -1

Answer:

Step-by-step explanation:

Triangle P is mapped onto Q so P is the initial triangle that will transformed.

We can rotate counterclockwise 90° but we cannot do it about the origin (0,0) because the red point (5, 1) will end up at ( -1, 5) .

We see that the point (5, 1)  ends up at ( -2, 4) so the center of rotation is lower than the origin.

The transformation is rotation of 90° about the point (0,-1)

Answer:

Look below

Step-by-step explanation:

I'm going to use B as my example to explain: B (-3,4)

You are going to need to draw a coordinate plane. When drawing the X axis, you want the highest X point to be 6 due to the fact that that is your highest x value. Then you want the lowest X point to be -6. Same will apply with the Y axis.

Next you are going to put a point in the middle of the plane which is called the origin (0,0).

Going from the origin, you want to follow the x axis the get to -3 which will be going left since its negative. Then since the Y axis is vertical, you are going to go up 4 times since the 4 is positive.

Then start from the origin for the next point being C (-5,4), Remember to always start from the origin.

Answer:

49

Step-by-step explanation:

Multiply out (a+b)^2

(a+b)^2 = (a+b)(a+b) = a^2 + ab + ba + b^2 ; not ab = ba so,

= a^2 + 2ab + b^2 = a^2 + b^2 + 2ab ; now subtitue in given values

=25 + 2(12) = 25 + 24 = 49

So (a+b)^2 = 49

Answer:

15/64

Step-by-step explanation:

Evaluate:

[(1/2)²-(1/4)³]

We have to find the value of expression ?

Explanation:-

Given that

[(1/2)²-(1/4)³]

⇛ [{(1/2)×(1/2)}-{(1/4)×(1/4)×(1/4)}]

⇛ [{(1×1)/(2×2)}-{(1×1×1)/(4×4×4)}]

⇛ [(1/4)-(1/64)]

LCM of 4 and 64 = 64

⇛ [(1×16)-(1×1)]/64

⇛ (16-1)/64

⇛ 15/64

The value of the given expression is 15/64.

Answer:

Scale factor = 2.5.

Step-by-step explanation:

Work out the lengths of the corresponding sides.

The scale factor is the ratio of one side to the other.

Take the smallest length in both triangles.

Blue triangle:

length = √((7.5-2.5)^2 + (12.5-5)^2) = 9.0139 units.

Red triangle:

length = √((3-1)^2 + (5-2)^2) =3.6056

So the scale factor

= 9.0139/ 3.6056

= 2.5.
