Simplify fully 4a sqaured +8a +2 I-a squared +9a -3
Answer:
The simplified expression is: [tex]3a^2 + 17a - 1[/tex]
Step-by-step explanation:
We are given the following expression:
[tex]4a^2 + 8a + 2 - a^2 + 9a - 3[/tex]
We can fully simplify the expression by combining the like terms. So
[tex]4a^2 + 8a + 2 - a^2 + 9a - 3 = 4a^2 - a^2 + 8a + 9a + 2 - 3 = 3a^2 + 17a - 1[/tex]
The simplified expression is: [tex]3a^2 + 17a - 1[/tex]

You must travel 295 miles to reach the next clue. In the first two hours of the trip you drive 115 miles. If you must reach the clue before time expires in 2.5 hours, at least how many miles should you travel each hour?
Answer:
Step-by-step explanation:
295 (miles to drive altogether) - 115 (miles already driven) = 180 (miles left to drive)
115 (miles already driven) / 2 (how many hours it took to reach 115 miles) = 57.5 (miles per hour)
180 (miles left to drive) / 57.5 (miles per hour) = 3.13 (hours it will take to reach the 295-mile mark at a rate of speed of 57.5 miles per hour)
So, you will have to drive more miles per hour than 57.5 miles per hour to be able reach the 295-mile goal, because it would take approximately 3 hours to drive the remaining 180 miles.
You will have to drive AT LEAST 72 miles each hour, and then 36 miles in the half hour to be able to reach the 295-mile mark.
I hope this helps, and is a thorough enough explanation :)

Answer:
530.66 square cm
Step-by-step explanation:
A=pi*r^2
A=pi*13^2
A=530.66
Answer:
A = 530.91 [tex]cm^2[/tex]
Step-by-step explanation:
The formula to find the area of a circle is ([tex]A = (pi)r^2[/tex]), where ([tex]A[/tex]) represents the area of the circle, ([tex]pi[/tex]) represents the value ([tex]3.1415...[/tex]), and ([tex]r[/tex]) represents the radius of the circle. Use this knowledge, and substitute in the given information, to solve for the area of the circle.
[tex]A = (pi)r^2\\\\A = (3.1415)(13)^2\\\\A = (3.1415)169\\\\A = 530.91[/tex]
What is the distance between (-6,0) and (5,3)?
Answer:
[tex]\sqrt{130}[/tex] or 11.4
Step-by-step explanation:
Use the distance formula:
d = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]
Plug in the points:
d = [tex]\sqrt{(-6 - 5)^2 + (0 - 3)^2}[/tex]
Simplify:
d = [tex]\sqrt{(-11)^2 + (-3)^2}[/tex]
d = [tex]\sqrt{121 + 9}[/tex]
d = [tex]\sqrt{130}[/tex]
= approximately 11.4
So, the distance is [tex]\sqrt{130}[/tex] or approx. 11.4

Actually Welcome to the Concept of the Statistics of a Categorised data.
We know that medium is the middle most point of any observation table or a Histogram displayed,
Hence we can clearly see here that, observation - 4 on the x-axis is the middle most entry of the Histogram, around which all other entries are equal.
===> Hence, option A.) 4 is correct answer.

The drawing shows a heart-shaped figure. The heart is composed of a square and two semicircles. The semicircles have the center in the middle of two of the sides.
a) Set up a formula to calculate the area of the heart.
Answer:
Area = πx² + x² or x²(π + 1)
Step-by-step explanation:
The area of the heart = area of a circle + area of the square
Note:
1. The 2 semicircles makes 1 full circle
2. The diameter of the circle = the side length of the square
Thus:
Area of the heart = πr² + s²
Where,
r = x
s = x
Formula for area of the heart = π(x²) + x² = πx² + x²
Area = x²(π + 1)

The side of a square was reduced by 3 in and the other side was enlarged by 5 in. The area of a new rectangle is 9 square inches. Find the side of a square
Answer:
4
Step-by-step explanation:
Give the other guy a 5 star my dude lol
The square has a property of having all the sides equal. The rectangle on the other hand has its opposite sides equal. The larger side of the rectangle is called length and the smaller side is called breadth. The area of rectangle is the product of length and breadth i.e.
[tex]\rm Area\:of\:rectangle = Length\: \times Breadth[/tex]
The side of square for the given question is [tex]4\rm \: inches[/tex].
Calculation:Let the side of square be [tex]\rm x[/tex]
Given:
Area of rectangle is 9 square inches.
Side of square is reduced by 3 and other side is enlarged by 5. Therefore, dimensions of the rectangle will be:
[tex]\rm Breadth = x - 3\\\\Length = x + 5[/tex]
[tex]\rm Area\:of\:rectangle = Length\: \times Breadth\\\\9 = (x + 5)(x -3)\\\\9 = x^2 + 5x -3x -15 \\\\9 = x^2 +2x - 15 \\\\0 = x^2 +2x-15-9\\\\0 = x^2+2x-24\\\\[/tex]
On factoring the equation:
[tex]\begin{aligned} \rm x^2 + 2x -24 &= 0\\\\x^2 + 6x - 4x - 24 &= 0\\\\x(x+6)-4(x+6) &= 0\\\\(x+6)(x-4)&=0\end[/tex]
On equating [tex]\rm (x +6)[/tex] and [tex](x-4)[/tex] with 0 we get:
[tex]x = -6\\\\x=4[/tex]
Since side of square cannot be negative, [tex]x = 4[/tex] is the only correct value.
Therefore the side of square is [tex]4 \:\rm inches[/tex].
