Answer:
Option B
Step-by-step explanation:
Given expression is,
(x² - 18x + 180)
Which is in the form of (ax² + bx + c)
To factorize the given expression, we will split b in two parts [tex]b_1[/tex] and [tex]b_2[/tex] so that,
[tex]b=b_1+b_2[/tex]
And [tex]c=b_1\times b_2[/tex]
If b = 18,
[tex]b_1=10[/tex] and [tex]b_2=8[/tex]
c = 10 × 8 = 80
Therefore, (x² - 18x + 180) = x² - 10x - 8x + 80
= x(x - 10) - 8(x - 10)
= (x - 8)(x - 10)
Option B is the correct option.

Answers
Answer:
[tex]\frac{4}{5}[/tex]
Step-by-step explanation:
If you have completed [tex]5[/tex] questions, you still have [tex]25-5=20[/tex] more questions to answer. We need to find what fraction [tex]20[/tex] is of [tex]25[/tex], if that makes sense. A fraction is simply a part over a whole. In this case, the part is [tex]20[/tex] and the whole is [tex]25[/tex]. Therefore, the fraction we are looking for is [tex]\frac{20}{25}[/tex], which simplifies to [tex]\frac{4}{5}[/tex]. Hope this helps!

The masses of four vehicles and the net forces acting on them as they enter a highway are recorded in the table below. Vehicle Mass (kg) Force (N) Sedan 1400 5250 SUV 1900 5250 Truck 2100 5250 RV 2500 5250 Which vehicle has the greatest acceleration as it enters the highway?
Answers
Answer:
if you use Newton's 2nd rule:
F = m* a (force = mass * acceleration)
you can rearrange the terms to:
a = F/m (acceleration = Force/mass)
which will let you solve for acceleration.
Juan thinks that the graph of 6y + 12x = 4 is a line. a. Solve Juan’s equation for y.
Answers
The equation of the line in the slope-intercept form will be y = 2/3 - 2x.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Juan thinks that the graph of 6y + 12x = 4 is a line.
Solve the equation of the line for y, then we have
6y + 12x = 4
6y = 4 - 12x
y = 4/6 - (12/6)x
y = 2/3 - 2x
The equation of the line in the slope-intercept form will be y = 2/3 - 2x.

z = 34
z = 17√2
z = 34√3
Answers
Answer:
Step-by-step explanation:
The first triangle right isosceles. The sides opposite the 45° angles are the same length.
x = 13
By the Pythagorean Theorem, y = 13√2
:::::
Second triangle is 30°-60°-90°. Remember that the sides of a 30°-60°-90° triangle are in the ratio 1:√3:2.
The side opposite the 30° has length 3, so the side opposite the 60° angle is 3√3 and the side opposite the 90° angle is 6.
x = 6
y = 3√3
:::::
The third figure has another 30°-60°-90° triangle. The side opposite the 30° angle is 17, so the side opposite the 60° angle is 17√3 and the side opposite the 90° angle is 2×17 = 34.
x = 17√3
The other triangle is right isosceles.
z = 34
y = 34√2
Radius of the circle is 20cm. there are two chords of lengths.
32cm, what will be the dis-
tance of these chords from
the centre of the circle?
Answers
9514 1404 393
Answer:
12 cm
Step-by-step explanation:
The distance to the chord is the median of an isosceles right triangle with hypotenuse 20 and leg 16. This 5:4 ratio suggests the other leg of that right triangle would make the ratios 3 : 4 : 5, so is 12.
The chords are 12 cm from the center.
_____
You can, of course, use the Pythagorean theorem. If c is half the chord length and d is the distance to the chord, you have ...
c² + d² = r²
16² + d² = 20²
d² = 400 -256 = 144
d = √144 = 12 . . . . . cm
