Answer:

first of all,

Step-by-step explanation:

In triangle ABC one side equal and two sides equal

Step-by-step explanation:

We are given a prism whose base is square with sides 8 in and height 12 in.

If we take cross section through vertices A, B and C

We will get a cross section as triangle.

In triangle ABC, sides are AB, BC and AC

AB is diagonal of top square whose side 8 in.

AC is face diagonal of front face.

BC is face diagonal of right face.

AC=BC≠AB

Hence, In triangle ABC one side equal and two side equal

Answer:

3rd option

Step-by-step explanation:

( $\frac{f}{g}$ )(x)

= $\frac{f(x)}{g(x)}$

= $\frac{2x^2-5x-3}{2x^2+5x+2}$ ← factorise numerator and denominator

= $\frac{(x-3)(2x+1)}{(x+2)(2x+1)}$ ← cancel (2x + 1) on numerator/ denominator

= $\frac{x-3}{x+2}$

Find the value of x that make it true

lesantik [10]

Answer:

Step-by-step explanation:

1). 10 = $\frac{1+7x}{7+x}$

10(7 + x) = 1 + 7x

70 + 10x = 7x + 1

10x - 7x = 1 - 70

3x = -69

x = -23

2). 0.2 = $\frac{6+2x}{12+x}$

0.2(12 + x) = 6 + 2x

2.4 + 0.2x = 6 + 2x

2.4 - 6 = 2x - 0.2x

1.8x = -3.6

x = -2

3). 0.8 = $\frac{x}{x+0.5}$

0.8(x + 0.5) = x

0.8x + 0.4 = x

x - 0.8x = 0.4

0.2x = 0.4

x = 2

4). 3.5 = $\frac{4+2x}{0.5-x}$

3.5(0.5 - x) = 4 + 2x

1.75 - 3.5x = 4 + 2x

-3.5x - 2x = 4 - 1.75

-5.5x = 2.25

x = - $\frac{2.25}{5.5}$

x = - $\frac{9}{22}$
