Answer:

[tex]\boxed{\boxed{\pink{\bf \leadsto Value \ of \ a \ is \ 5cm \ and \ b \ is \ 2cm .}}}[/tex]

Step-by-step explanation:

Given that the area of PQRS is 45 cm²

Area of PXYS = 10cm²

Now , from the figure we can see that ,

[tex]\bf\implies SY + YR = SR \\\\\bf\implies PX+XQ = PQ [/tex]

Also , we see that ,

[tex]\bf\implies ar(PSYX)= PS\times SY \\\\\bf\implies ar(XYRQ) = XY\times RQ [/tex]

And , we know that area of rectangle as ,

[tex]\large\boxed{\red{\bf Area_{rectangle}=lenght\times breadth }}[/tex]

Finding a :-

[tex]\implies\bf ar(XYRQ) = XY\times RQ \\\\\bf\implies ( 45cm^2-10cm^2) = 7cm\times a \\\\\bf\implies 7a = 35cm^2 \\\\\bf\implies a =\dfrac{35cm^2}{7cm}\\\\\bf\implies\boxed{\red{\bf a = 5cm}}[/tex]

Finding b :-

[tex]\implies\bf ar(PSYX)= PS\times SY \\\\\bf\implies 10cm^2 = b \times 5cm \\\\\bf\implies b =\dfrac{10cm^2}{5cm} \\\\\bf\implies\boxed{\red{\bf b = 2cm}}[/tex]

Hence the value of a is 5cm and b is 2cm .

-6x-1=23

=> -6x=1+23

=> -6x=24

=> x= 24/-6

=> x= -4

Hope it helps!

Step-by-step explanation:

Hey there!

Given;

[tex] - 6x - 1 = 23[/tex]

~ Shift "-1" on right side.

[tex] - 6x = 23 + 1[/tex]

[tex] - 6x = 24[/tex]

~Divide 24 by -6.

[tex]x = \frac{24}{ - 6} [/tex]

Therefore, x= -4.

If x = 12 and y = 3, what is the value
of |-x + 5y|?

Answers

Answer:

3

Step-by-step explanation:

First, let's solve whats in the absolute value. If wee plug in the values of x and y, we get -(12) + 5(3) which is -12 + 15. This equals to 3. Now concerning the absolute value, it makes the value inside it always positive. And since the answer is positive, that means it remains the same.

Answer:

I don't know if im correct but the missing side on P is 9 and the missing side on Q is 28? Sorry if im wrong

Step-by-step explanation:

7x 4 = 28cm

36÷4= 9cm

P= 9cm

Q= 28cm

What are similar Triangles?

Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.

In similar triangles, corresponding sides are always in the same ratio.

By the given figure ABC and XYZ,

We check the ratios of corresponding sides

XY/AB=YZ/CB=XZ/AC

16/4=36/CB=XZ/7

4=36/CB=XZ/7

Now equate the equation to get the unknown lengths.

4=36/CB

CB=36/4

=9

So CB=9

XZ/7=4

XZ=28

So lengths of XZ is 28 and length of CB is 9.
