I believe it would be 29 because a supplementary angle is 2 angles that equal 180 so I would think to do 189-151=29

If the length of a rectangular yard is represented by w+4 and the width by 2w+5, write a simplified expression in terms of w tha
adell [148]

Answer:

P = 6w + 18

Step-by-step explanation:

A rectangle is a plane shape having a LENGTH and a WIDTH.

Length (l) = w + 4

Width (w) = 2w + 5

To write a simplified equation in terms of w to represent the total length, let's used the idea of a PERIMETER of a RECTANGLE.

Perimeter (P) = 2 ( l + b)

Where l = length= w + 4

Where b = width = 2w + 5

P = 2( w + 4 + 2w + 5)

P = 2( 3w + 9)

P = 6w + 18

For which value of x is the figure a rhombus?
zysi [14]

Answer:

D. x = 7

Step-by-step explanation:

The labeled angles are the acute angles of a right triangle, so they are complementary. Their measures add up to 90 deg.

8x + 7 + 3x + 6 = 90

11x + 13 = 90

11x = 77

x = 7

The price of a watch was increased by 20% to £162. <br> What was the price before the increase?
Inessa [10]

Answer:

The answer is 135

Step-by-step explanation:

We can use formula: 162...120% since the price was increased by 20% which means it is 120%

So: 162...120%

x.... 100%

120x = 16200 => x = 135

The sum of the roots of 3x 2 + 11x - 4 = 0 is<br><br> -11/3<br> -4/3<br> 11/3<br> 4/3
givi [52]

Answer:

The correct option is 1.

Step-by-step explanation:

If a quadratic equation is defined as

ax^2+bx+c=0             .... (1)

Then the sum of the roots is -b/a and the product of roots is c/a.

The given equation is

3x^2+11x-4=0          ... (2)

From (1) and (2) we get a=3, b=11 and c=-4.

The sum of roots is

\frac{-b}{a}=-\frac{11}{3}

The sum of roots is -\frac{11}{3}.

Therefore the correct option is 1.
