Answer:
A 33 degrees
Step-by-step explanation:
[tex]x \degree = 180 \degree - (23 \degree + 124 \degree) \\ \\ x \degree = 180 \degree - 147 \degree\\ \\ x \degree = 33 \degree \\ \\ x = 33[/tex]
Answer:
A) 33
Step-by-step explanation:
the angles of a triangle always add up to 180.
124 + 23 + x = 180
combine like terms
147 + x = 180
147 + x - 147 = 180 - 147
x = 180 - 147
x = 33

Step-by-step explanation:
(Ax² + Bx + C)²
= (Ax² + Bx + C)(Ax² + Bx + C)
= Ax⁴ + 2ABx³ + 2ACx² + 2BCx + C².
By Comparing Coefficients, we have:
A = 1
2AB = 6
2AC = 7
2BC = a
C² = b
Solving them we get A = 1, B = 3 and C = 3.5.
Therefore a = 2BC = 2(3)(3.5) = 21,
b = C² = (3.5)² = 12.25.

simplify (y + 1)^5y + 1)^3
Answers
Note: Your expression sounds a little unclear, so I am assuming your expression is
[tex]\left(y\:+\:1\right)^5\times \left(y\:+\:1\right)^3[/tex]
But, the procedure to solve the expressions involving exponents remains the same, so whatever the expression is, you may be able to get your concept clear.
In the end, I will solve both expressions.
Answer:
Please check the explanation
Step-by-step explanation:
Given the expression
[tex]\left(y\:+\:1\right)^5\times \left(y\:+\:1\right)^3[/tex]
solving the expression
[tex]\left(y\:+\:1\right)^5\times \left(y\:+\:1\right)^3[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\times \:a^c=a^{b+c}[/tex]
[tex]\left(y+1\right)^5\left(y+1\right)^3=\left(y+1\right)^{5+3}[/tex]
[tex]=\left(y+1\right)^8[/tex]
Therefore, we conclude that:
[tex]\left(y\:+\:1\right)^5\times \left(y\:+\:1\right)^3=\left(y+1\right)^8[/tex]
IF YOUR EXPRESSION IS THIS
↓
[tex]\left(y\:+\:1\right)^{\left(5y+1\right)^3}[/tex]
solving the expression
as
[tex]\left(a+b\right)^3=a^3+3a^2b+3ab^2+b^3[/tex]
so
[tex]\left(5y+1\right)^3=125y^3+75y^2+15y+1[/tex]
[tex]=125y^3+75y^2+15y+1[/tex]
Thus, the expression becomes
[tex]\left(y+1\right)^{\left(5y+1\right)^3}=\left(y+1\right)^{125y^3+75y^2+15y+1}[/tex]

Considerando las siguientes variables a = ancho y l = longitud, determina su valor, si se sabe que se cuenta con un rectángulo que tiene como perímetro 35 metros, y se sabe que el doble de su ancho es igual a 3 veces su longitud.
Answers
Answer:
La longitud = 7 metros
La anchor = 10.5 metros
Step-by-step explanation:
La fórmula para el perímetro de un rectángulo es
P = 2L + 2W
L = longitud
A = ancho
P = 35 metros
se sabe que el doble de su ancho es igual a 3 veces su largo.
2A = 3L
Ancho = 3L / 2 = 1.5L
Sustituimos 1.5L por W
35 = 2 L + 2 (1.5 L)
35 = 2L + 3L
35 = 5 litros
L = 35/5
L = 7 metros
Por lo tanto, la longitud = 7 metros
Recuerda
A = 1.5 L
A = 1.5 × 7
A = 10.5 metros
La anchor = 10.5 metros

Answers
Answer:
861 (approx)
Step-by-step explanation:
It is given that there is a note of 20 dirham. The 20 dirham note is 13 cm long. And we have to place the 20 dirham notes to cover a length of 112 m without overlapping the notes.
We know that :
100 cm = 1 m
∴ 13 cm = 0.13 m
In order to cover a length of 112 m, we have to divide 112 by 0.13, i.e.
[tex]$=\frac{112}{0.13}$[/tex]
[tex]$=\frac{11200}{13}$[/tex]
= 861 (approx)

I have solved the second equation for x. What is the next step if solving this system with substitution?
A. -(5y+2) + y = 5
B. -x + y = 5 + 5y + 2
C. None of the Above
D. -x + 5y + 2 = 5
Answers
Answer:
A. -(5y+2) + y = 5
Step-by-step explanation:
Solving the above Equation given to us in the Question,
-x + y = 5...... Equation 1
x - 5y = 2....... Equation 2
Step 1
We make x subject of the formula in Equation 2
---> x= 5y + 2
Step 2
This would be to substitute 5y + 2 for x in Equation 1
-x + y = 5...... Equation 1
-(5y+2) + y = 5
Hence, Option A is the correct option
What is the slope of the line do the point for me to?
Answers
Answer:
Step-by-step explanation:
we can see that the line goes thru the point (-1,2) and (4,-2) now to find slope we just find change in y over change in x
more visually:
(y1-y2)/(x1-x2)
so for the point (-1,2) let’s say
-1 = x1
and
2 = y1
and for the point (4,-2) let’s say
4 = x2
and
-2 = y2
to find slope we plug in the values to our slope equation and we get this:
(2-(-2))/( -1-4)
(2+2)/-5
4/-5
so slope is -4/5
because to get from (-1,2) to (-4,-2) you have to move down 4 and to the right 5
