Explanation

Machine language is a low-level language

It consists of binary code (0s and 1s) that is directly executed by a computer's CPU.

High-level languages like C, Java, and Fortran are designed to be more user-friendly and abstracted from machine code.

Explanation

The present perfect tense is formed using: has/have + past participle

In this case: Subject: She → use has

The past participle of lose is lost

So, the correct sentence is: She has lost her keys.

Explanation

He misses his friend a lot.

"He" is third person singular, so the verb "miss" takes an -es ending in the simple present tense:

miss→misses

Explanation

When we use under as a preposition,

it is similar to below.

We use under to talk about something that is below or lower than something else:

The cat is under the table.

Explanation

This book is mine.

"mine" is a possessive pronoun that stands alone and replaces a noun.

The other options are incorrect:

my → possessive adjective (needs a noun after it: my book)

me → object pronoun (e.g., Give me the book.)

I → subject pronoun (e.g., I have the book.)

Explanation

An expression consisting of two terms is called a binomial.

A binomial is a polynomial with two terms, such as: 2x + 3

Monomial: An expression with only one term, such as 2x or 3.

Trinomial: An expression with three terms, such as 2x + 3y - 4.

Additional points:

• Polynomial: An expression consisting of variables and coefficients combined using only addition, subtraction, and multiplication.
• Multinomial: An expression with more than two terms.
• Uninomial: An expression with only one term (synonym for monomial).

Explanation

The past perfect tense is formed using:

had+past participle

(a) I have finished my work. → Present perfect

(b) I finished my work. → Simple past

(d) I was finishing my work. → Past continuous
