Find and simplify an expression for the area of two rows of b squares with side lengths of b centimeters .
Answer:
2b³ cm²
Step-by-step explanation:
The Area of each square :
Area of a square = a² ; where a = side length
The side length = b
Hence, Area, A = b² = b² cm²
The total number of squares:
Number of rows * number of squares per row
2 * b = 2b
Therefore, total area :
Total number of squares * area of each square
(2b) * b²
= 2b³ cm²
Each month Marla pays a $30 cell phone bill from her bank account. At the
end of one year, what is the change in the amount of money in Marla's account
because of her cell phone bill? Write a multiplication equation to represent the
problem. Explain what the product represents.
Answer:
-$360.00 change
Step-by-step explanation:
Now there is either some information missing, like her starting total in the bank; or they want you to explain the net change. But the way the question is worded it is stating she is paying $30 over 12 months. This means she has paid $360.00 in that 12 months aka 1 year. Her bank account should have had a balance. So you could technically say B for balance. B-30*12. To get your answer. Although there are many ways to write an equation expression of this question. If you know the starting balance then it's better. But you could assume her starting balance was $0. Which would be 0-30M*12 where M could represent monthly. And the same answer would occur of 360. Is there more information?
30*12= X (x equals the total paid)
X-30*12 (if x is her balance before paying any money)

Matrix A has 2 rows and 3 columns whereas matrix B has3 rows and 2 column
Can AB be multiplied? Can BA be multiplied? Give the reason
Step-by-step explanation:
for any matrix multiplication number of columns of first matrix should be equal to number of rows of second matrix.
For AB
A has 3 columns and B has 3 rows so it matches . Hence can be multiplied.
For BA
B has 2 columns and A has 2 rows it also matches so can be multiplied

Solve for the area of this triangle, explanation would be greatly appreciated!
9514 1404 393
Answer:
13√731 ≈ 351.48 cm²
Step-by-step explanation:
When given three sides of a triangle, there are a number of ways that the area may be calculated. Perhaps the most straightforward is the use of Heron's formula.
Where s is the semi-perimeter, the area is given by ...
A = √(s(s -a)(s -b)(s -c)) . . . . . . . . s = (a+b+c)/2
Here, the value of s is ...
s = (30 +30 +26)/2 = 43
A = √(43(13)(13)(17)) = 13√(43·17)
A = 13√731 ≈ 351.48 . . . . . square centimeters
_____
Additional comments
This triangle is isosceles, so the altitude can be found from the Pythagorean theorem:
h² +13² = 30²
h = √(900 -169) = √731
Then the area is ...
A = (1/2)bh = (1/2)(26 cm)(√731 cm) = 13√731 cm²
__
You can also find one of the angles using the Law of Cosines, then find the area from ...
Area = (1/2)a·b·sin(C) . . . . . . for any two sides a, b, and enclosed angle C
__
Ultimately, all of these methods are equivalent to Heron's formula.

tan(A—B)=tanA—tanB/1+tanAtanB
Answer:
tan (A−B)=tan(A)−tan(B)/1+tan(A)tan(B)tan(A−B)=tan(A)−tan(B)/1+tan(A)tan(B)
1+tan(A)tan(B) To prove this, we should know that:
1+tan(A)tan(B) To prove this, we should know that:sin(A−B)=sin(A)cos(B)−cos(A)sin(B)

7)
60°
x + 83
40°
A) 7
C) -5
B) -11
D) -3
Answer:
-3
Step-by-step explanation:
Using the Triangle Sum Theorem, we can prove that m<A + m<B + m<C = 180⁰. Looking at the triangle above, it has given us two measurements. We have to find the third measurement. In order to find the third measurement we will use the Triangle Sum Theorem.
m<A + m<B + m<C = 180⁰
x + 83 + 60⁰ + 40⁰ = 180⁰
x + 183⁰ = 180⁰
x + 183⁰ - 183⁰ = 180⁰ - 183⁰
x = -3
Now plug in -3 in the x place.
x + 83
-3 + 83 = 80⁰
Let us make sure that our Triangle Sum Theorem is right.
m<A + m<B + m<C = 180⁰
80⁰ + 60⁰ + 40⁰ = 180⁰
180⁰ = 180⁰
So this makes our answer true. Hope this helps, thank you :) !!

Answer:
g(x) = 3x^2 -2
Step-by-step explanation:
Reflection in the y-axis replaces x with -x.
g(x) = f(-x) = 3(-x)^2 -2
g(x) = 3x^2 -2
_____
The given function is symmetrical about the y-axis, so its reflection is itself.

HELP ASAP
Answer:
Please include the details of the angle
Step-by-step explanation:
When the angle is 93 degrees, the the angle is a obtuse angle. option B is correct.
Given that the measure of angle A is 93 degrees, we can classify the angle as follows:
Angle A = 93 degrees
We know that if angle is less than 90 degrees, it is acute.
if angle is greater than 90 degrees, it is obtuse.
if angle is equal to 90 degrees, it is right angle.
Since the angle measures greater than 90 degrees, it falls within the range of an obtuse angle.
Therefore, the correct classification for angle A is obtuse.

Paul has a collection of nickels and
dimes that has
a total value of
& 12.50. He Has 150 coins in all. How
many dimes does paul have?
Answer:
#nickels = 50
#dimes = 100
Step-by-step explanation:
system of equations:
n + d = 150
.05n + .10d = 12.50
let n = '150 - d' and substitute this into the second equation
.05(150-d) + .10d = 12.5
7.5 - .05d + .10d = 12.5
.05d = 5
d = 5/.05
d = 100
n = 50
