Answer:
x=22/p
Step-by-step explanation:
1. Add 18 to 4
2. px=22
3. Divide by p to isolate x
4. 22/p=x
the slant height would be the hypotenuse of a right triangle. 1/2 the length of the base would be one side of a right triangle. Use the Pythagorean theorem to find the height:
89.9^2 = 9.9^2 + x ^2
8082.01 = 98.01 + x^2
X^2 = 8082.01-98.01
X^2 = 7984
X = sqrt(7984)
X = 89.35
Round to 89.4
Answer:
Step-by-step explanation:
<u>a) (x2 - 4)/(x + 2)</u>
We can simply use factorization to solve the given question.
Here the first term will be numerator and second term will be denominator.
We will factorize the numerator.
So,
Using formula,
<u>b) (4x2 - 1) / (2x + 1)</u>
We can simply use factorization to solve the given question.
Here the first term will be numerator and second term will be denominator.
We will factorize the numerator.
Using formula,
Hence,
Answer:
x=63
Step-by-step explanation:
Because we know that the total angle is a right angle (see the square in the top right of the problem), and 25 and x+2 constitute as the only two angles making up the total angle, we can say that 25 and x+2 are complementary, meaning they add up to 90 degrees. We can then write our equation as follows:
25 + (x+2) = 90
27+x=90
Subtract 27 from both sides
x=63
Answer:
C
Step-by-step explanation:
(–3, 4) and (2, 8)
y2 = 8, y1 = 4, x2 = 2 and x1 = -3
Slope m = {y2-y1}/{x2-x1}
m = {8 - 4}/{2 - (-3)}
m = 4/(2+3)
m = 4/5
And
y - y1 = m(x - x1)
y - 4 = 4/5(x - (-3))
y - 4 = 4/5(x + 3)
Multiply each term by 5
5y - 20 = 4(x + 3)
5y - 20 = 4x + 12
5y = 4x + 20 + 12
5y = 4x + 32
Dividing by 5
y = 4x/5 + 32/5
y = 0.8x + 6.4
