The value of the expression is -53.
What is an expression?An expression or algebraic expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them.
Given expression
m2 - 71 +22..................(1)
m = -2 and n = 5
Substitute m = -2 and n = 5 in equation(1)
⇒ m2 - 71 +22
⇒ (-2) × 2 - 71 + 22
⇒ -4 -71 +22
⇒ -75 + 22
⇒ -53
Hence, the value of the expression is -53.

Is it possible for the measure of an exterior angle of a triangle to be equal to the measure of a remote interior angle? Explain
Answer:
The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles. (Non-adjacent interior angles may also be referred to as remote interior angles.) FACTS: An exterior ∠ is equal to the addition of the two Δ angles not right next to it.

How do you find area and perimeter of a rectangle with the side lengths of 5x^2 and 12x?
Answer:
The area can be found by multiplying the two terms, and the perimeter by doubling and adding them.
Using this, we find that the area of the rectangle is 60x³, and the perimeter is 10x² + 24x.
Step-by-step explanation:
First let's find the area:
5x² × 12x
= 60x³
Now the perimeter:
2(5x² + 12x)
= 10x² + 24x

The line CD passes through the points C (2, -1) and D (1, 1). Which of the
following represents the equation of the line in Point-Slope Form?
Answer:
The equation of the straight line in point - slope form
y +1 = -2 ( x-2)
Step-by-step explanation:
Step(i):-
Given points are C( 2,-1) and D(1,1)
Slope of the line
[tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} } = \frac{1-(-1)}{1-2} = \frac{2}{-1} = -2[/tex]
m = -2
Step(ii):-
Equation of the straight line passing through the point ( 2,-1) and having slope
m =-2
y - y₁ = m ( x- x₁)
y - (-1) = -2 ( x-2)
y +1 = -2 ( x-2)
Final answer:-
The equation of the straight line
y +1 = -2 ( x-2)
can anyone please help me with this
Answer:
no
Step-by-step explanation:
The correct explanation is A
[tex]\frac{x^{m} }{a^{n} }[/tex] = [tex]a^{(m-n)}[/tex]
Thus
[tex]\frac{9.2}{4}[/tex] × [tex]\frac{10^{8} }{10^{-3} }[/tex]
= 2.3 × [tex]10^{(8-(-3))}[/tex]
= 2.3 × [tex]10^{11}[/tex]

An ice cream factory makes 375 quarts of ice cream in 5 hours. How many quarts could be made in 13 hours?
Answer:- 975 quarts of Ice cream is prepared in 13 hours.
Step-by-step explanation:
If 375 quarts of ice cream is made in 5 hours
then in 1 hour quantity of ice cream prepared is = 375/5=75
then in 13 hour quantity of ice cream prepared would be = 13×75=975 quarts.

Approximate Value Exact Value Error Absolute Error Ratio Percent Error
$100
$75
$25
How much was the absolute error in his estimate?
$
Intro
Answer:
Absolute error = $25
Step-by-step explanation:
Given that:
Amount spent by John on shopping trip = $75
Estimated amount to spent on shopping trip = $100
Absolute error = Approximate value - Exact value
Here,
Approximate value = $100
Exact value = $75
Absolute error = 100 - 75
Absolute error = $25
Percentage = [tex]\frac{Absolute\ error}{Exact\ value}*100[/tex]
Percentage = [tex]\frac{25}{75}*100[/tex]
Percentage = 33.33%
Hence,
Absolute error = $25
