Step-by-step explanation:
The equation is given as;
−4(x−3)=20
Gwendolyn's flaw is in the following lines;
−4x + 12 = 20
−4x = 32
When collecting like terms, the moment 12 crosses over, it becomes - 12 and not + 12
The correct solution is given as follows;
Step 1: Expand the brackets
This results to;
- 4x - (-4 * 3) = 20
-4x + 12 = 20
Step 2: Collect like terms
This results to;
- 4x = 20 - 12
- 4x = 8
Step 3: Solve for x
x = 8 / (-4)
x = -2

Your 80 year-old uncle goes to the doctor and says he has a positive test for prostate cancer. He comes to you and says, "You are studying math and statistics. I heard there can be false positive tests." What is the chance I actually have prostate cancer, based on my positive test? Show how you would find this probability, and then explain to him what the answer means. (Remember, you are looking at the probability of a false positive, out of all of the total positive tests)

Answer:
A Scalene
B Isosceles
C Equilateral
Explanation: Interior angles are all different To see why this is so, imagine two angles are the same. The triangle would then be an Isosceles triangle, which has two sides the same length. Similarly, if all three angles are the same, it would be an equilateral triangle and all three sides would be the same length.

Can someone please help me with 1,2 please
Answer:
1) This HAS a right angle
2) This is an obtuse triangle
Step-by-step explanation:
1)
4² + 3² = 5²
16 + 9 = 25
25 = 25 ✅
2)
5² + 6² = 8²
25 + 36 = 64
61 ≠ 64 ❌
Since c is bigger, this is an obtuse triangle

Diego deposited $5,000 at a rate of 6.25 % for 20 years . Find the simple interest and amount of money Diego had in the bank after 20 years.
Answer:
First find the rate for a year .
5000 dollars × 6.25 = 31 250
After you find it multiply it by 20 ( because there are 20 years)
31 250 × 20 = 625000
Answer:
Diego had 6,250 in the bank after 20 years.
Step-by-step explanation:

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(8, 5) = 40. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 5 = 40. In the next intermediate step the fraction result cannot be further simplified by canceling.

What is the remainder when (2x^3 - 5x^2 + 3x + 7) is divided by (x - 2)?
Answer:
remainder = 9Step-by-step explanation:
(x - 2) => x = 2
f(x) = f(2)
___________= 2x³ - 5x² + 3x + 7
= 2(2)³ - 5(2)² + 3(2) + 7
= 2×8 - 5×4 + 6 + 7
= 16 - 20 + 6 + 7

Find the value of x in the triangle shown below 16 12
please put a valid explanation for the answer
Answer:
x=10
Step-by-step explanation:
Pythagorean Thereom: a^2+b^2 = c^2 when the triangle is right which it is since the 90 degree angle is marked.
a=8 and b=6
8^2+6^2= 64+36 = 100
Take the square root of 100 and get 10.
