Let's see what to do buddy...
____________________________
Reminder:
[tex](a + b)(a - b) = {a}^{2} - {b}^{2} [/tex]
So we need to just Multiply above equations like this :
[tex]x + y = 70[/tex]
[tex]x - y = 40[/tex]
[tex](x + y)(x - y) = 70 \times 40[/tex]
[tex] {x}^{2} - {y}^{2} = 2800 [/tex]
____________________________
And we're done.
Thanks for watching buddy good luck.

Solve for x in the following equation:
kx = m + nx
Answer:
x = [tex]\frac{m}{k-n}[/tex]
Step-by-step explanation:
Given
kx = m + nx ( subtract nx from both sides )
kx - nx = m ← factor out x from each term on the left side
x(k - n) = m ← divide both sides by (k - n)
x = [tex]\frac{m}{k-n}[/tex]
Solving for x in the equation, kx = m + nx, we would make x the subject of the formula to solve for x as: [tex]\mathbf{x = \frac{m}{k - n}}[/tex]
Given:
kx = m + nx
We are require to make x the subject of the formula.Thus:[tex]kx = m + nx[/tex]
Subtract nx to both sides of the equation[tex]kx - nx = m + nx - nx\\\\kx - nx = m[/tex]
Factor out x on the left side[tex]x(k - n) = m[/tex]
Divide both sides by (k - n)[tex]\frac{x(k - n)}{k - n} = \frac{m}{k - n} \\\\x = \frac{m}{k - n}[/tex]
Therefore, solving for x in the equation, kx = m + nx, we would make x the subject of the formula to solve for x as: [tex]\mathbf{x = \frac{m}{k - n}}[/tex]

Find the equation of the line passing through the point (-1, -2) and perpendicular to
the line y = -1/2x + 5.
A) y = 2x
O B) y = -1/2x - 5/2
O C) y = -1/2x
OD y = 1/2x - 5,2
Answer:
A) y = 2x
Step-by-step explanation:
The slopes of perpendicular lines are negative reciprocals.
The given line has slope -1/2.
The negative reciprocal of -1/2 is 2.
The only choice with slope = 2 is choice A.
y = 2x does include point (-1, 2).
Answer: A) y = 2x
He value of variable for which the polynomial becomes zero is called as the zeroes of the polynomial. For Example: Consider p(x) = x + 2. Find zeroes of this polynomial. (i) If we put x = -2 in p(x), we get, (ii) p(-2) = -2 + 2 = 0. (iii) Thus, -2 is a zero of the polynomial p(x)
OK this is hard math
Evaluate if x = -3, y = -2, and z = 11:
x(4y + z)²
If x = -3, y = -2 and z = 11, we can plug it into the equation provided.
x(4y + z)²
-3(4(-2) + (11))²
-3(-8 + (11))²
-3(-8 + (11))²
-3(3)²
-3(9)

1, 6, 15, 20, 15, 6, 1
1, 5, 10, 10, 5, 1
1, 4, 6, 4, 1
Answer:
1, 6, 15, 20, 15, 6, 1
Step-by-step explanation:
The binomial expansion of (p + q)⁶ gives 1, 6, 15, 20, 15, 6, 1.
There is always one more extra term for each power;
(p + q)⁰ = 1
(p + q)¹ = 1 1
(p + q)² = 1 2 1
(p + q)³ = 1 3 3 1
(p + q)⁴ = 1 4 6 4 1
(p + q)⁵ = 1 5 10 10 5 1
(p + q)⁶ = 1 6 15 20 15 6 1
The above is a paschal triangle and which shows the coefficients of the expanded terms to their power.
Answer: B: 1, 6, 15, 20, 15, 6, 1

Sam found that 25% of the 236 patients he saw in a week were near-sighted. How many of the patients Sam saw were near-sighted?Sam found that 25% of the 236 patients he saw in a week were near-sighted. How many of the patients Sam saw were near-sighted?
Answer:
59 patients
Step-by-step explanation:
Total patients Sam saw in a week = 236
Percentage of patients near-sighted = 25%
How many of the patients Sam saw were near-sighted?
Number of patients near-sighted = 25% of 236
= 25/100 × 236
= 0.25 × 236
= 59
Number of patients near-sighted = 59 patients
The number of patients Sam saw in a week that were near-sighted is 59 patients

ax +3= 6
Solve for x.
Answer:
Step-by-step explanation:
Let's solve for a.
ax+3=6
Step 1: Add -3 to both sides.
ax+3+−3=6+−3
ax=3
Step 2: Divide both sides by x.
ax /x = 3 /x
a= 3 /x
Answer:
a= 3 /x
Answer:
ax = 3
Step-by-step explanation:
ax + 3 = 6
Subtract 3 from both sides of the equation
ax = 3

mZBAC =
mZCAD =
Answer:
In the pic
Step-by-step explanation:
If you have any questions about the way I solved it, don't hesitate to ask me in the comments below :)
The ∠BAC is 58° and ∠CAD is 32° for the given figure.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
In another word, the angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.
Given,
∠BAD = 90°
Since,
∠BAD = ∠BAC + ∠CAD
15x - 2 + 7x + 4 = 90°
22x = 88 ⇒ x = 4
So,
∠BAC = 15(4) - 2 = 58°
And
∠CAD = 7(4) + 4 = 32°
Hence "The ∠BAC is 58° and ∠CAD is 32° for the given figure".
