Answer:
A) CPCTC
Step-by-step explanation:
This part of the proof occurs right after two triangles are proven congruent. One could now conclude and establish that every part of each congruent triangle is congruent, which is what is most likely happening in this scenario.
Which of the following correctly completes the square for: x^2+2x=48
A. (x+2)^2=52
B. (x+1)^2=49
C. (x+2)^2=47
D. (X-1)^2=26
Answer:
(x+1)²= 49, the answer is B
Step-by-step explanation:
x² + 2x = 48
x² + 2x + (2/2)² - (2/2)²= 48 --[what we are trying to do is to complete a square by adding (2/2)² - (2/2)²]
(x+1)²= 49, the answer is B
Answer:
hey I'm pretty sure it's B. (x+2)²=49
Step-by-step explanation:
x²+2x+(2\2)²=48 + (2\2)²
(x+1)²=49

cos B = O.05. what is the approximate measure of angle B
The value of the measure of angle B will be;
⇒ ∠ B = 87.13°
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The value is,
⇒ cos B = 0.05
Now,
Since, The value is,
⇒ cos B = 0.05
Taking cos inverse both side, we get;
⇒ cos⁻¹ cos B = cos⁻¹ 0.05
⇒ B = 87.13°
Thus, The value of angle B = 87.13°

Ren built a birdhouse with a volume of 224 in.3 Find the height of the birdhouse.
Complete question:
Ren built a birdhouse with a volume of 224 in³ Find the height of the birdhouse. A square pyramid. The square base has side lengths of 8 inches and the height is unknown.
Answer:
the height of the birdhouse is 10.5 in.
Step-by-step explanation:
Given;
volume of the square pyramid, V = 224 in³
length of a side of the square base, a = 8 in
The volume of square pyramid is calculated as;
[tex]V = \frac{a^2h}{3} \\\\where;\\h \ is \ height \ of \ the \ birdhouse \ (Pyramid)\\\\a^2h = 3V\\\\h = \frac{3V}{a^2} \\\\h = \frac{3 \times 224}{8^2} \\\\h = 10.5 \ in[/tex]
Therefore, the height of the birdhouse is 10.5 in.

The cost of an article including 15% for taxes is ghc ghc138. What is the cost of the article without taxes
Answer:
Cost of article before tax is 120.
Step-by-step explanation:
It says cost of an article including 15% tax is 138.
So, let the cost of article without tax as 'x'
So, we can set up equation as
x+15%(x)=138
Simplify it
x+0.15x=138
1.15x=138
Divide both sides by 1.15
x=120
So, cost of article before tax is 120.

Are the following two expressions equivalent?
Explain how you know...
3(4-x)
6(x+2)-7x
Answer:
no, because the first=12-x
and the second=-1x+2
Step-by-step explanation:
Answer:
No, they are not equivalent.
Step-by-step explanation:
First, we simplify the two expressions.
3(4 - x) = 12 - 3x We multiply everything inside the bracket by 3.
6(x + 2) - 7x = 6x + 12 - 7x = 12 - x Using BODMAS/BIDMAS, we first multiply everything in the brackets by 6 and then simplify.
If we compare 12 - 3x to 12 - x, we can clearly notice that they aren't equivalent. If they were to be equivalent, they would have to be exactly the same values as each other. The 12 is common in both expressions, but the -3x and -x differ, therefore the following two expressions aren't equivalent.

Step-by-step explanation:
[tex]C=\pi d[/tex]
[tex]9=\pi d\\\frac{9}{\pi } =d\\[/tex]
calculate the diameter of the circle
Answer:
2.64cm
Step-by-step explanation:
A = π r^2
5.5 = π r^2
1.75 = r^2
r = 1.32
Diameter is then 2(1.32) = 2.64
Answer:
2.65 cm to the nearest hundredth
Step-by-step explanation:
A = πr^2 = 5.5
r^2 = 5.5/ π = 1.5707
r = 1.3231
Diameter = 2 * r
= 2.6462.
