Answer: A=x^2+7x+12
Step-by-step explanation:
A=area of triangle. h=height. b=base
A=bh/2
A=(x+4)(2x+6)/2
A=(x+4)(2x/2+6/2)
A=(x+4)(x+3)
A=x*x+4x+3x+4*3
A=x^2+7x+12

I need help with this someone help me please!!
Answer:
Option 4
Step-by-step explanation:
Finding Area
The area of the semicircle is
[tex](\pi/2)(4^2) \approx (3.14/2)(16)=25.12[/tex]
The area of the trapezoid is
[tex]\frac{1}{2}(8+20)(8)=112[/tex]
Adding these, we get the area to be about 137.12 square inches.
Finding Perimeter
The arc length of the semicircle is
[tex]\pi(4) \approx 3.14(4)=12.56[/tex]
The sum of the lengths of the outer sides of the trapezoid is
[tex]10+10+20=40[/tex]
Adding these, we get the area to be about 52.56 inches.
is it less, greater or equal pls help (will give brainleist)

Midpoint Formula: [tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]Step-by-step explanation:
Step 1: Define
Point (5, 6)
Point (5, 3)
Step 2: Find Midpoint
Substitute: [tex](\frac{5+5}{2},\frac{6+3}{2})[/tex]Add: [tex](\frac{10}{2},\frac{9}{2})[/tex]Divide: [tex](5,\frac{9}{2})[/tex]Answer:
(5, 4.5)
Step-by-step explanation:
You would want to use the midpoint formula to find the midpoint of line 5,6 and 5,3.
Midpoint formula = [tex]\frac{x1 + x 2}{2} , \frac{y1 + y2}{2}[/tex]
x1 = 5
x2 = 5
y1 = 6
y2 = 3
Plug those into the midpoint formula.
[tex]\frac{5+5}{2} , \frac{6+3}{2}[/tex]
5+5=10/2 = 5
6+3=9/2=4.5
you answer will be (5,4.5)

You have to spend money to make money. You purchase three social media advertisements for every one newspaper ad you end up purchasing a total of 24 advertisements
Answer:
x = 3y
x + y = 24
The number of social media advertisement purchased is 18
And, the number of newspaper advertisements purchased is 6
Step-by-step explanation:
Let us assume the number of social media advertisement purchased be x
And, the number of newspaper advertisements purchased be y
As three social media advertisements for every one newspaper advertisement is purchased
So,
y = x ÷ 3
x = 3y
And it is ended by total of 24 advertisement
That means
x + y = 24 ............(1)
Now put the value of x in equation 1
3y + y = 24
4y = 24
y = 24 ÷ 4
= 6
x = 3y
= 6 × 3
= 18
Now The equations are
x = 3y
x + y = 24

3/5 divided by 2 1/2
Step-by-step explanation: To divide mixed numbers, first rewrite the mixed numbers as improper fractions.
So here, 3/5 is already a fraction and 2 and 1/2 can be written as 5/2.
Remember that dividing by a fractions means the same thing
as multiplying by the reciprocal of that fraction.
In other words, 3/5 ÷ 5/2 can be rewritten as 3/5 · 2/5.
Finally, multiplying across the numerators and the
denominators, we have 6/25.
The result of the division of 3/5 divided by 2 1/2 is: 6/25.
Here, we have,
given that,
3/5 divided by 2 1/2

Approximating
1. Approximate to the nearest tenth: v45
Approximation to the nearest tenth means to find the tense place . e.g.
25632 - in this case the '32'
then you round it upwards or downwards according to rule that if digit at once place is
from 0 - 4 you round downwards,
from 5 - 9 you round upwards for example
25632 goes to 25630
248 goes to 250
Therefore approximate to nearest tenth means to make the number a nearest multiple of 10 with respect to the rule that if digit at once place is
from 0 - 4 you round downwards,
from 5 - 9 you round upwards
Look at the next place value to the right to round a number to the nearest tenth (the hundredths). Remove all the digits to the right if it's 4 or less. If it's 5 or higher, add 1 to the digit in the tenths place before removing all the digits to the right.

Which expression is equivalent to 4(x + 3) - 2(-x - 5)?
Answer:
the last one because when using the distributive property, you get
4x + 12 - 2x - 10
Answer:
4x + 12 + 2x + 10
Step-by-step explanation:
4( x + 3 ) -2( -x -5 )
1. Multiply 4 and x = 4x
2. Multiply 4 and 3 = 12
3. Multiply -2 and -x = 2x
(turns positive as there are 2 negative signs)
4. Multiply -2 and -5 = 10
(turns positive as there are 2 negative signs)

Piper paid for 3 boxes of cookies to be
delivered to her house.
• Each box of cookies cost $24.95.
• Piper paid $12.99 for delivery.
What is the total amount Piper paid?
Answer:
Total Amount Paid by Piper = $84.87
Option C is correct.
Step-by-step explanation:
Total boxes of cookies = 3
Cost of 1 box of cookie = $24.95
Delivery charges paid = $12.99
We need to find total amount Piper paid.
First we will find cost of 3 boxes of cookies:
Cost of 1 box of cookie = $24.95
Cost of 3 box of cookie = $24.95 x 3
= $74.85
Now, add cost of 3 boxes of cookies with delivery charges paid to get total amount paid.
Total Amount Paid = Cost of 3 box of cookie + Delivery charges paid
= 74.85 + 12.99
= 87.84
So, Total Amount Paid by Piper = $84.87
Option C is correct.

Step-by-step explanation:
Find the unit rate for all and compare
1.05/3=0.35
1.75/5=0.35
2.8/8=0.35
Since they are all equal, there proportional
Answer:
y = 0.35x
Step-by-step explanation:
Jane:
Cost of 3 postcards= $1.05
Cost of 1 post card = 1.05 ÷ 3
= $ 0.35
Rosi:
Cost of 5 postcards= $1.75
Cost of 1 post card = 1.75 ÷ 5
= $ 0.35
Tanya:
Cost of 8 postcards= $2.80
Cost of 1 post card = 2.80 ÷ 8
= $ 0.35
As unit rate is same, Cost and number of postcards are in proportion.
Cost of cards = 0.35 * number of cards
y = 0.35*x
y = 0.35x
On each of Maggie’s bird-watching trips, she has seen at least 36 birds. If she has taken 3 of these trips each year over the past 15 years, at least how many birds has Maggie seen?
Answer:
Maggie has seen at least 1620 birds.
Step-by-step explanation:
Ok since Maggie sees 36 birds each trip that means she sees 108 birds every year since she takes 3 trips each year. 36×3=108
If she has been doing this for 15 years she has seen at least 1620 birds because 108×15=1620
