Yes <span>because if you multiple numerator and denominator of 3/4 by 10 then you would get 30 / 40.

Another way to look at is to notice that 30 = 3</span>×10 and 40 = 4×10

So that's 30 / 40 = ( 3×10 ) / ( 4×10 ) = 3 / 4 because 10 was cancelled, therefore they are equivalent to each other.

The width of a rectangle measures (2.5u+9.8)(2.5u+9.8) centimeters, and its length measures (1.5u+3.9)(1.5u+3.9) centimeters. Wh
icang [17]

Solution,

We have,

Width of rectangle, b = (2.5u+9.8) cm

Length of rectangle, l = (1.5u+3.9) cm

We need to find the expression for the perimeter of the rectangle. The formula for the perimeter of a rectangle is given by:

Perimeter = 2(l+b)

P = 2[(2.5u+9.8)+(1.5u+3.9)]

Collecting like terms

P = 2[(2.5u+1.5u)+(9.8+3.9)]

P=2(4u+13.7)

⇒ P = 8u+27.4

So, the expression for the perimeter of the rectangle is (8u+27.4) cm.

The angle measurements in the diagram are represented by the following expressions.
AfilCa [17]

Given:

\angle A=10 x+24^{\circ}

\angle B=6 x+72^{\circ}

To find:

The value of x and measure of ∠A.

Solution:

Let C be angle the vertically opposite to ∠A.

The reference image for answer is attached below.

By vertical angle theorem:

m∠A = m∠C

m∠C = 10x + 24°

By the corresponding angle theorem:

m∠C = m∠B

10x + 24^\circ = 6x+72^\circ

Subtract 24° on both sides.

10x = 6x+48^\circ

Subtract 6x from both sides.

4x=48^\circ

Divide by 4 on both sides.

x = 12^\circ

The value of x is 12°.

\angle A=10 x+24^{\circ}

     =10 (12^{\circ})+24^{\circ}

     =144^\circ

The measure of ∠A is 144°.
