The perimeter of the equilateral triangle shown is 67.5 inches. Write and solve an equation to find the value of x.
Answers
Answer:
The answer is 14. Not -14.
Step-by-step explanation:
The value of x for the given triangle will be 14.
What is an expression?The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
Given that the perimeter of the equilateral triangle shown is 67.5 inches. One side of the triangle is 1.75x - 2.
Perimeter = 3 ( 1.75x - 2 )
67.5 = 5.25x -6
x = ( 73.5 / 5.25 )
x = 14
Therefore, the value of x for the given triangle will be 14.

Answer:
∠B = 82°
Step-by-step explanation:
(see attached for reference)
recall the property that an exterior angle of a triangle is equal to the sum of its two remote interior angles.
in our case, the exterior angle is obtuse ∠A = 143°
the two remote interior angles are ∠C and ∠B
hence according to our definition above:
143° = ∠C + ∠B (we are given that ∠C =61°)
hence
143° = 61° + ∠B
143° - 61° = ∠B
∠B = 82°

Write an equation of the parabola in intercept form that passes through (-2,0.05) with x-intercepts of -7 and -3.
Answers
Answer:
y = 0.01(x +7)(x +3)
Step-by-step explanation:
For intercepts p and q, the equation will be ...
y = a(x -p)(x -q)
For the given intercepts, the equation is ...
y = a(x +7)(x +3)
We can find the value of 'a' by using the given point:

How do I find the domain and range of a graph?
Answers
The domain is the x-axis and the range is the y-axis.
To find the domain, you measure or count the widest part of this oval horizontally. So that is 3 units to the right of 0 and 3 units to the left of 0. I counted it exactly on the axis because that is the widest part of the oval.
To find the range, you again count or measure the widest part of the oval vertically. So that is 4 units above 0 and 4 units below 0.

-3x + y = 22 ⇒ y = 3x + 22
-12x - 10y = -10 and y = 3x + 22
-12x - 10(3x + 22) = -10
-12x - 30x - 220 = -10

Answers
The equivalent fractions for 2/3 are 6/9, 10/15, and 12/18 because multiplicative identity is a feature of multiplication that is used to determine equivalent fractions.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
2/3 by multiplying by 3/3, 5/5, and 6/6.
= (2/3)(3/3)
= 6/9
= (2/3)(5/5)
= 10/15
= (2/3)(6/6)
= 12/18
The multiplicative identity is a feature of multiplication that is used to determine equivalent fractions.
The numerator and denominator of a fraction are multiplied by the same number for determining equivalent fractions.
Thus, the equivalent fractions for 2/3 are 6/9, 10/15, and 12/18 because multiplicative identity is a feature of multiplication that is used to determine equivalent fractions.

Miguel did the following math problem: 65 ∙ 64 = 369. Which of the following is a true statement? 1.He is correct. 2.He is incorrect because he should have subtracted the exponents. 3.He is incorrect because he should have multiplied the exponents. 4.He is incorrect because he multiplied the bases.
Answers
Answer:
He is incorrect.
Step-by-step explanation:
The correct answer is 4,160.
Answer:
3. He is incorrect because he should have multiplied the exponents.
Step-by-step explanation:
6∧5 × 6∧4 = 369 Incorrect
Correct: 6∧5 = 7776
6∧4 = 1296
7776 × 1296 = 10,077,696
1. He is not correct, therefore the first answer is wrong.
2. You do not subtract the exponents unless one of the exponents is negative and you have the same bases. You have the same bases in this equation, however, neither one of them are negative. Therefore, the second answer is wrong.
3. The third answer is correct because if you were adding the two terms together then you would add the exponents together then multiply the base as many times as needed. However, since you are multiplying the two terms together, you also need to multiply the exponents together. From there, you then multiply the terms and get your answer.
4. The fourth answer is also incorrect because you need to multiply the bases together in order to get a correct answer.
