Hello!

<h3><em><u>Answers</u></em></h3>

1. $\frac{7}{10} + \frac{2}{10} = \frac{9}{10}$ Simplest form: $\frac{9}{10}$

2. $\frac{13}{16} + \frac{2}{16} = \frac{15}{16}$ Simplest form: $\frac{15}{16}$

3. $\frac{4}{5} + \frac{1}{5} = \frac{5}{5}$ Simplest form: $\frac{1}{1}$

4. $\frac{7}{15} + \frac{2}{15} = \frac{9}{15}$ Simplest form: $\frac{3}{5}$

5. $\frac{9}{20} + \frac{3}{20} = \frac{12}{20}$ Simplest form: $\frac{3}{5}$

6. $\frac{5}{8} + \frac{1}{8} = \frac{6}{8}$ Simplest form: $\frac{3}{4}$

<h3><em><u>Explanation:</u></em></h3>

If B is the midpoint of AC and AB = 4x + 14 and BC = x + 20, determine how long AC is.

Serhud [2]

Answer:

44 units

Step-by-step explanation:

Since B is the mid-point of AC

AB=BC

or,4x+14=x+20

or, 4x-x=20-14

or 3x=6

or,x=6/3=2

AC=AB+BC

= 4x+14+x+20

= 4(2) + 14 +2 +20

= 8+14+22

=44 units

To find the surface area of the pyramid, in square inches, Vikram wrote (33.2) (34.2) + 4 (one-half (34.2) (28.4)). What error d

madam [21]

Answer:

B. He used the wrong expression to represent the area of the base of the pyramid.

Step-by-step explanation:

Given

See attachment for pyramid

$Area = (33.2)(34.2) + 4 * \frac{1}{2} * 34.4 * 28.4$

Required

Vikram's error

The surface area of a square pyramid is:

$Area = Base\ Area + 4 * Area \triangle$

Where

$Base\ Area = Length * Length$

$Base\ Area = 34.2 * 34.2$

$4 * Area \triangle = 4 * \frac{1}{2} * Base * Height$

$4 * Area \triangle = 4 * \frac{1}{2} * 34.2 * 28.4$

So:

$Area = Base\ Area + 4 * Area \triangle$

$Area = 34.2 * 34.2 + 4 * \frac{1}{2} * 34.2 * 28.4$

By comparing the calculated expression with

$Area = (33.2)(34.2) + 4 * \frac{1}{2} * 34.4 * 28.4$

Option (b) is correct
