Answer:
1) 23a + 18
2) 23a - 6
3) 23a - 18
4) -16
5) 7a - 6
Step-by-step explanation:
Use the distributive property (if it is subtraction remember to distribute the negative sign as well)
1) 3(5a + 2) + 4(2a + 3) = (15a + 6) + (8a + 12) = 23a + 18
2) 3(5a + 2) + 4(2a - 3) = (15a + 6) + (8a - 12) = 23a - 6
3) 3(5a - 2) + 4(2a - 3) = (15a - 6) + (8a - 12) = 23a - 18
4) 3(5a - 2) - 5(3a - 2) = (15a - 6) - (15a +10) = 15a - 6 - 15a - 10 = -16
5) 3(5a + 2) - 4(2a + 3) = (15a + 6) - (8a + 12) = 15a + 6 - 8a - 12 = 7a - 6
Try doing the rest :)

Nicholas bought a new computer for $1,250. The value of the computer decreases by 17 percent every year. Approximately how much is the computer worth after 5 years?
Answer: The computer worth $ 492.38 after 5 years.
Step-by-step explanation:
If the value of an item depreciates by r% then the value of the item after t years is given by :-
[tex]V=V_0(1-\dfrac{r}{100})^{t}[/tex]
, where [tex]V_0[/tex] = initial value.
Given: [tex]V_0[/tex] =$1,250, r=17% , t= 5 years
Then, the value of computer after 5 years = [tex]1250(1-\dfrac{17}{100})^5[/tex]
[tex]=1250(0.83)^5\\\\=1250(0.39390)\\\\\approx492.38[/tex]
Hence, the computer worth $ 492.38 after 5 years.

1. Given that ABCD is a rhombus with ∠DBC=49∘, what is ∠DAB?
A. 82 degrees
B. 90 degrees
C. 49 degrees
D. 98 degrees
2. In a rhombus FGHJ, m∠JKF=(3y+6)∘ and m∠KFG =(7y−14)∘. Find the value of y?
A. 20
B. 10
C. 8
D. 5
Answer:
1). Option (A)
2). Option (D)
Step-by-step explanation:
1). We will use two properties of the rhombus,
- Diagonals of a rhombus are perpendicular and bisect each other.
- Diagonals of a rhombus bisect the opposite angles.
From the figure attached,
m∠DBC = 49° [Given]
m∠DBA = 49° [m∠DBC = m∠DBA]
In ΔAOB,
m∠AOB + m∠OBA + m∠BAO = 180° [Triangle sum theorem]
90°+ 49° + m∠BAO = 180°
m∠BAO = 41°
Since, m∠DAB = 2(m∠BAO)
= 2(41°)
= 82°
Option (A) will be the answer.
2). From the figure attached,
m∠JKF = (3y + 6)°
m∠KFG = (7y - 14)°
Since, m∠JKF ≅ m∠KFG
(3y + 6) = (7y - 14)
7y - 3y = 6 + 14
4y = 20 ⇒ y = 5
Option (D) will be the answer.

When solving an equation, Francesca's first step is shown below. Which property
justifies Francesca's first step?
Original Equation:
- 2x + 2 = -4
First Step:
-2x = -6
The property justifies Francesca's first step is subtracting 2.
Here,
Original Equation is,
- 2x + 2 = -4
First step is,
-2x = -6
What is the equation?
An equation is made up of expressions that equal each other.
Now,
Original Equation is,

On a piece of paper, use a protractor to construct A ABC with mZA = 30mZB= 60° and mZC = 90
Which statements about the triangles are true?
Select each correct answer
1. АС
2.AC > BC
3. AC > AB
4.AC < BC
Answer:
In short, Your Answer would be Option 1.AC < AB & 2.AC > BC
Step-by-step explanation:
Here, we know largest side is always opposite to the largest angle.
As largest angle is C with 90 degree, it's opposite side which is AB must be longest here!! & AC would be second largest & BC would be smallest
The statement about the triangle is given as AB > AC > BC
What is a triangle?
A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, scalene, equilateral and right angled triangle.
The size of a triangle side is proportional to the angle opposite to the side.
m∠A = 30, m∠B= 60° and m∠C = 90. Hence: AB is the greatest followed by AC and then BC
AB > AC > BC
The statement about the triangle is given as AB > AC > BC
