A triangle has a base of 4x+2 and a height of x+4. Find the area.
Answers
Answer:
15 height
Step-by-step explanation:
Answer:
2x^2 + 9x + 4
Step-by-step explanation:
To find the area of a triangle, use the formula, 1/2 · base · height = area.
If we plug the given expressions into the formula, we get
1/2(4x+2)(x+4)
Which simplifies to
(2x+1)(x+4)
=2x^2 + 9x + 4

Answer:

Step-by-step explanation:
The explicit rule for the given geometric sequence is aₙ = a₁rⁿ⁻¹ = 1000 x 1.2ⁿ⁻¹
What is a geometric sequence?A geometric sequence is a special type of sequence where the ratio of every two successive terms is a constant.
Given that, in two years the deer population in a state forest was 1,200. In year 4, the population was 1,728,
Therefore,
a₄ = 1728 and a₂ = 1200
We have two terms of the GP, therefore, finding r,
r² = 1728 / 1200 = 1.44
r = 1.2
Therefore,
a₁ = a₂r¹⁻²
= 1200r⁻¹ = 1200/r
= 1200 / 1.2 = 1000
Therefore, the formula will be = aₙ = a₁rⁿ⁻¹ = 1000 x 1.2ⁿ⁻¹
Hence, the explicit rule for the given geometric sequence is aₙ = a₁rⁿ⁻¹ = 1000 x 1.2ⁿ⁻¹

The area of a rectangle is base x height
The area of the two triangles is 2 x [(base x height*)/2]
12cm x 5cm = 60cm2
2 x (12cm x 4cm)/2) = 2 x (48cm2/2) = 2 x 24cm2 = 48cm2
60 + 48 = 108cm2
base or rect - 12cm
base of triangle - 12cm
height of rect - 5cm
height of triangle - 13cm - 5cm = 8cm /2 = 4cm for each triangle

Step-by-step explanation:
Let x represent the first number. Then the second is x-9. The other relation is ...
4x = 2(x-9) -6
2x = -24 . . . . . subtract 2x, simplify
x = -12
x-9 = -21
The first number is -12; the second number is -21.

The distances traveled make an arithmetic series, the sum of which is given by ...
Sn = (2·a1 +d(n -1))(n/2)
This series has first term a1=5 and common difference d=7. Then the total distance traveled in 30 seconds is ...

Answers
Answer:
first one
just subtract 21 from each number
Answer:
C - {873, 894, 915, 936, …}
Step-by-step explanation:
Difference means subtraction. So, subtract -21 from the number to get your next value.
1245 - (-21) = 1266 So, A is not the answer
32 - (-21) = 53 So, B is not the answer.
873 - (-21) = 894 So, C is the answer.
1563 - (-21) = 1584 So, D is not the answer.
To double check, subtract -21 from the other numbers too.
873 - (-21) = 894
894 - (-21) = 915
915 - (-21) = 936
and so on...
This matches up with the list of numbers on option C so it it correct.
I hope this helps you Cheers!

what is 452÷6 in long division
Answers
Answer: 75.333333...
Step-by-step explanation: Might want to round that number to the nearest tenths. This number is a repeating digit.
Here we will show you step-by-step with detailed explanation how to calculate 452 divided by 6 using long division.
Before you continue, note that in the problem 452 divided by 6, the numbers are defined as follows:
452 = dividend
6 = divisor
Step 1:
Start by setting it up with the divisor 6 on the left side and the dividend 452 on the right side like this:
6 ⟌ 4 5 2
Step 2:
The divisor (6) goes into the first digit of the dividend (4), 0 time(s). Therefore, put 0 on top:
0
6 ⟌ 4 5 2
Step 3:
Multiply the divisor by the result in the previous step (6 x 0 = 0) and write that answer below the dividend.
0
6 ⟌ 4 5 2
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (4 - 0 = 4) and write the answer below.
0
6 ⟌ 4 5 2
- 0
4
Step 5:
Move down the 2nd digit of the dividend (5) like this:
0
6 ⟌ 4 5 2
- 0
4 5
Step 6:
The divisor (6) goes into the bottom number (45), 7 time(s). Therefore, put 7 on top:
0 7
6 ⟌ 4 5 2
- 0
4 5
Step 7:
Multiply the divisor by the result in the previous step (6 x 7 = 42) and write that answer at the bottom:
0 7
6 ⟌ 4 5 2
- 0
4 5
4 2
Step 8:
Subtract the result in the previous step from the number written above it. (45 - 42 = 3) and write the answer at the bottom.
0 7
6 ⟌ 4 5 2
- 0
4 5
- 4 2
3
Step 9:
Move down the last digit of the dividend (2) like this:
0 7
6 ⟌ 4 5 2
- 0
4 5
- 4 2
3 2
Step 10:
The divisor (6) goes into the bottom number (32), 5 time(s). Therefore put 5 on top:
0 7 5
6 ⟌ 4 5 2
- 0
4 5
- 4 2
3 2
Step 11:
Multiply the divisor by the result in the previous step (6 x 5 = 30) and write the answer at the bottom:
0 7 5
6 ⟌ 4 5 2
- 0
4 5
- 4 2
3 2
3 0
Step 12:
Subtract the result in the previous step from the number written above it. (32 - 30 = 2) and write the answer at the bottom.
0 7 5
6 ⟌ 4 5 2
- 0
4 5
- 4 2
3 2
- 3 0
2
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 452 divided by 6 calculated using Long Division is:
75

How high off the ground is the top of the monument?
Please help
Answers
Answer:
65 meters
Step-by-step explanation:
The height of the monument off the ground = x + 5
Find x using Pythagorean Theorem:
x = √(61² - 11²)
x = √3,600
x = 60 meters
Height of the monument off the ground = x + 5 = 60 + 5 = 65 meters
