Answer:
- 10a² + a + 4
Step-by-step explanation:
( 12a² + 6a - 8 ) + ( - 22a² + 12 - 5a )
= 12a² + 6a - 8 - 22a² + 12 - 5a
= 12a² - 22a² + 6a - 5a + 12 - 8
= - 10a² + a + 4
Answer:

What is the slope of the line that contains the points (-1, 2) and (3, 3)?
Answer:
[tex]\text Slope = \frac{1}{4}[/tex]
Step-by-step explanation:
the slope of the line that passes through the points
[tex]\large A\left( x_{1},y_{1}\right) \text{and} \ B\left( x_{2},y_{2}\right)[/tex]
[tex]\large \text{slope} =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Sonia will go on a 9-day vacation with his grandparents. He will take $57 of his
own money. His grandparents will give him another $78. Sonia will spend all
of the money and he will spend the same amount each day. How many dollars
will Sonia spend each day of the vacation?
Answer:
$15
Step-by-step explanation:
Sonia will take $57, and his grandparents will give another $78. 57 + 78 = 135. Sonia will have 135 dollars, but it is a 9 day vacation, so 135/9 = 15
Sonia will spend 15 dollars a day.
One angle of a triangle measures 20°the other two angles are in a ratio of 3:5. What are the measures of those two angles?
Answer:
180-20 = 160 = sum of the other two angles

A. Chloe should have added the numbers and divided by 9.
The median is 46.
B. Chloe did not make a mistake; the median is 37.
C. Chloe forgot to arrange the numbers in ascending order. The median is 44.
D. The median is the number which appears the most; there is no median.
Answer:
C. Chloe forgot to arrange the numbers in ascending order. The median is 44.
Step-by-step explanation:
We arrange the 9 numbers of the data from the least to the greatest
Then we spot the middle number (5th number) which is 44:
34 < 37 < 38 < 42 < 44 < 51 < 55 < 56 < 57

Find the area of the shaded region. (Blue is the shaded region)
Answer:
135ft^2
Step-by-step explanation:
area of trapzoid= (a+b)/(2)×h
area of traingle= 1/2(b)(h)
area of the shaded region equals (a+b)/(2)×h-1/2(b)(h)
so
(8+18)/(2)×15-(1/2)(8)(15)
=135ft^2
please find the area of the shaded region
Answer:
Step-by-step explanation:
Remark
The way to solve the shaded region is to find the area of the square first and subtract the area of the circle from it.
Area of the square
Area = s^2
s = 12
Area of the square = 12 * 12
Area of the square = 144 yd^2
Area of the circle = pi * r^2
r = d/2
d is actually the same as the side length of the square
r = 12/2
r = 6
pi = 3.14
Area of the circle = pi * 6^2
Area of the circle = 3.14 * 36
Area of the circle = 113.04
Area of the shaded region
Area of shaded region = area of the square - area of circle
Area of shaded region = 144 - 113.04
Answer: Area of the shaded region 30.96

What is the area of a parallelogram with a base of 26 m and a height of 18 m?
Answer:
468 m²
Step-by-step explanation:
Given:
→ Base = 26 m
→ Height = 18 m
Formula:
[tex]\text{Area of parallelogram: Base} \times \text{Height}[/tex]
To determine the area of the parallelogram, we need to substitute the base and the height in the formula.
Substitute the measures in the formula:
[tex]\implies \text{Area of parallelogram: Base} \times \text{Height}[/tex]
[tex]\implies \text{Area of parallelogram} = 26 \times 18[/tex]
Evaluate the area of the parallelogram:
[tex]\implies \text{Area of parallelogram} = 26 \times 18[/tex]
[tex]\implies \text{Area of parallelogram}= \bold{468 \ \text{m}^{2}}[/tex]
Answer:
468 m²
Step-by-step explanation:
Given,
Base ( b ) = 26 m
Height ( h ) = 18 m
To find : The area of parallelogram
Formula : -
Area of parallelogram = bh
Area of paralleogram
= 26 x 18
= 468 m²
Therefore,
the area of the parallelogram is 468 m².

Answer:
B which is 2/4.
Step-by-step explanation:
Elin: worked for 2/4 + 1/4 = 3/4 of an hour on an assignment
Jocyln worked for 5/4 of an hour the same assignment
The difference in time is 5/4 - 3/4 = 2/4 or 1/2 hour.

An equation is formed of two equal expressions. The solution of the equation √(x+12)=x is x=4.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The solution of the equation √(x+12)=x can be done as,
[tex]\sqrt{x+12} = x\\\\\text{Square both the sides of the equation}\\\\x+12=x^2\\\\x^2-x-12=0\\\\x^2-4x+3x-12=0\\\\x(x-4)+3(x-4)=0\\\\(x-4)(x+3)=0[/tex]
Equate each of the factors with 0,
[tex](x-4)=0\\x=4\\\\(x+3)=0\\x=-3[/tex]
Now, if we substitute the value of x in the equation given, only the value of x as 4 will satisfy the equation.
Thus, the solution of the equation √(x+12)=x is x=4.

Scott received a score of 91, 85, and 89 on three tests. What score must Scott get on the fourth test to have an overall average score of 90
Answer:
95
Step-by-step explanation:
So if you wanted to figure the average of the 3 tests, you would add 91+85+89 to get 265 & then divide by 3 tests to get an average of 88.
So that means for four tests, 91+85+89+4th test = answer that divided by 4 tests will equal 90. 90 x 4 = 360. Then 360 -265 (sum for 1st 3 tests) = 95

The figure below represents a top view of Johns patio. What is the value of X?
Answer:
The value of x = 110°
Step-by-step explanation:
=> x° + 90° + 90° + 70° = 360 ° { sum of angles of a quadrilateral is 360 }
=> x + 250° = 360°
=> x = 360 - 250
=> x = 110°
