Aloiza [94]

Step-by-step explanation:

To find - Enter five expressions: a sum, a difference, a product, a quotient, and one that involves at least two operations that have the value of -3/4 (the fraction)

Solution -

Expression for sum is -

1/4 + (-1) = -3/4

Expression for difference is -

(1/4 - 1) = -3/4

Expression for product is -

(-3/2)(1/2) = -3/4

Expression for quotient is -

(1 - 4)/4 = -3/4

Expression that involves at least two operations is -

-(1/4 + 2/4) = -3/4

In the figure shown the value of a is equal to

Vikentia [17]

Answer:

a = 7.2

Step-by-step explanation:

The figure has been re-labelled and attached to this response.

From the figure, the larger right triangle DAB and the small right triangle BCA are similar. This is because;

i. They have two corresponding congruent angles which are<em> the right angle</em>

and <em>angle B</em>

Therefore, we can say that;

$\frac{|DB|}{|BA|} = \frac{|AB|}{|BC|}$

$\frac{13}{a} = \frac{a}{4}$

<em>Cross multiply</em>

a x a = 13 x 4

a² = 52

a = √52

a = 7.2

Note: The figure showing the similar triangles has also been attached to this response.
