Step-by-step explanation:
A=l×b
=(2a+b)(3a+c)
=6a²+2ac+3ba+bc
hope it helps.
Answer:
6a^2+2ac+3ab+b^2
Step-by-step explanation:
Given
length=2a+b
breadth=3a+c
Now,
Area=?
We know,
Area=l*b
(2a+b)*(3a+c)
2a(3a+c)+b(3a+c)
6a^2+2ac+3ab+b^2
You can use formula (a+b)^2
a^2+2ab+b^2

if thrice my age 6 years ago be subtracted from twice my present age the result is present age then my present age is what
Answer:
9 years
Step-by-step explanation:
Let the present age = x
Age 6 years ago = x - 6
Thrice my age 6 years ago = 3*(x -6) =3x - 3*6 = 3x - 18
Twice my present age = 2 *x = 2x
Thrice my age 6 years ago be subtracted from
twice my present age = 2x - (3x - 18)
2x - (3x - 18) = x
2x - 3x + 18 = x
-x + 18 = x {Add x to both sides}
18 = x + x
18 = 2x {Divide both sides by 2}
18/2 = x
x = 9 years

Sara is making 3 batches of chocolate chip
cookies and 3 batches of oatmeal cookies.
Each batch of chocolate chip cookies uses
2 cups of flour. She will use 122 cups of
flour for all six batches. Determine how
many cups of flour are needed for each
batch of oatmeal cookies.
3 batches of chocolate chip with 2 cups per batch is 6 cups total for the chocolate chip cookies.
Subtract the total needed for the chocolate chip from the total flour used, then divide the remaining amount by number of batches of oatmeal
Cookies.
The problem show 122 total cups, but I don’t think that is right... what is the actual total cups used?

Use the number line to find each measure
Answer:
ST = 3 units
Step-by-step explanation:
From the number line attached in the picture,
Distance of S from 0 = 7 units
Distance of T from 0 = 4 units
Therefore, distance between S and T = 7 - 4
ST = 3 units
[Note : Length of a segment is always positive so ST can't be negative]

hey! can anyone help me? thanks in advancee teehee
Step-by-step explanation:
1 week = 7 days
Therefore 1 week = 60,000 letters
=> 7 days = 60,000 letters

Hence Obama receives around 8,571 letters per day.
Find the sum of the first 90 terms of the sequence –4, –1, 2, 5, 8, ...
a.
11654
c.
11656
b.
11657
d.
11655
Answer:
D. 11655
Step-by-step explanation:
First find the 90th term:
a90=a1+(n−1)d
= -4+89(3)=263
Then find the sum:
Sn = n(a1 + an) / 2
S90 = 90 (-4 + 263) /2
S90 = 23,310/2
S90 = 11,655

Another question my friend asked me and I pretended to know what I was doing. I’m lost help
Answer:
x = 107
Step-by-step explanation:
The exterior angle and the interior angle make a supplementary angle.
This means it is 180°. Knowing this, we can solve for x:
73 + x = 180
x = 107
Therefore, x = 107.

60.2
Step-by-step explanation:
a^2 + b^2 = c^2
40^2 + 45^2 = c^2
1600 + 2025 = c^2
3625 = c^2
the square root of 3625 is 60.2
Answer:
60.2 metres
Step-by-step explanation:
Pythagoras formula = square of b plus squar of c = square of a
let b be 40 and let c be 45
40^2 + 45^2 = a^2
1600 + 2025 = a^2
3625 = a^2
square root of 3625 = a
