Answer:
A mathematical equation or phrase that includes numbers, variables, and operators.
Step-by-step explanation:
Examples of numbers: 1, 5, 60, 100
Examples of variables: a, x, y
Examples of operators, +, -, x, /
Any mathematical equation with all 3 of the given examples is called an algebraic expression.
For example:
1 + 21 is not an algebraic expression, because although it has both numbers and operators, it does not have a variable.
x + 2 is an algebraic expression, because it has all 3 of the components listed above.
Hope I helped :)
Answer:
-3/22
Step-by-step explanation:
Mulitiply straight across. Num * num/ denom * denom.
Now you have -6/44. Divide both by 2 to simplify into simipliest form.

Answer is -15</h3>
We read this out as "negative 15" or you could write "negative fifteen".
The negative indicates the temperature went down. It doesn't necessarily mean that the final temperature is -15 degrees.
For example, if it starts being 50 degrees F, and drops by 15 degrees, then 50+(-15) = 50-15 = 35 degrees is the temperature after that drop. It might help to use a vertical number line.
The answer is “translation followed by a dilation” :)
<u>Given</u>:
Given that the triangular prism with height 10 inches.
The side lengths of the base of the triangle are 12 inches, 13 inches and 5 inches.
We need to determine the surface area of the prism.
<u>Surface area of the prism:</u>
The surface area of the prism can be determined using the formula,
where b is the base and h is the height of the triangle.
s₁, s₂, s₃ are the side lengths of the triangle and
H is the height of the prism.
Substituting b = 12, h = 5, s₁ = 12, s₂ = 5, s₃ = 13 and H = 10 in the above formula, we get;
Thus, the surface area of the triangular prism is 360 square inches.
Hence, Option b is the correct answer.
