Answer:
x = 9
Step-by-step explanation:
(x+1)²-(x-1)² = 6(x-3)
x²+2x+1-x²+2x-1 = 6x-18
x²-x²+2x+2x+1-1 = 6x-18
4x = 6x-18
4x-6x = -18
-2x = -18
x = -18/-2
x = 9

A cuboid is 12 cm broad and 10 cm high. If its volume is 1800 cm³, find its length.
Answer:
it's length is 15cm
Step-by-step explanation:
let a represent the length
a × 10 ×12 = 1800
a×120= 1800
a = 1800÷12
a=15cm
1800=L×h×b
1800=L×10×12
1800=120L
L=1800/120
L=15cm ans..
Write the equation of the parabola graphed below given the y-intercept is (0, 1)
Brainliest gets 45 points so please help ASAP
Answer:
y = -3/8(x - 4)² + 7 or y = -3/8x² + 6x + 1Step-by-step explanation:
We can see on the graph that the vertex is (4, 7) and the leading coefficient is negative as parabola opens down.
The vertex form is:
y = a(x - h)² + k, substitute coordinates to get,y = a(x - 4)² + 7Considering the y-intercept is (0, 1), substitute values to find the value of a:
1 = a(0 - 4)² + 7a(4²) = 1 - 716a = -6a = -6/16a = -8/3The function is:
y = -3/8(x - 4)² + 7In standard form:
y = -3/8(x² - 16x + 16) + 7 = -3/8x² + 6x - 6 + 7 = -3/8x² + 6x + 116

Find the exact value of z.
a² + b² = c²
First find out the length of the line in the middle. We know that a² + 16² = 27², which means a = √473
Now write out all the equations for all the right triangles in the diagram.
Let the side of the base of the triangle be x and the remaining sides of z be y.
x² + 27² = (16+ y)²
y² + (√473)² = x²
From here solve and find y. Once you get y, y + 16 is your z, the answer.

Kevin, Luke and mat share £200 in the ratio 1:4:3 how much more money does Luke receive than Kevin
Answer:
£75
Step-by-step explanation:
sum the parts of the ratio, 1 + 4 + 3 = 8 parts
Divide the amount by 8 to find the value of one part of the ratio
£200 ÷ 8 = £25 ← value of 1 part of the ratio, then
4 parts = 4 × £25 = £100 ← Luke's share
Thus
£100 - £25 = £75
Luke receives £75 more than Kevin

Formula of area
AREA = LENGTH (multiply) BREATH
Answer:
The area of a triangle can be calculated with the formula: 1/2(bh), where b is the base length, and h is the height.
In this case, 4 is the base, and 7 is the height.
So we have: Area = 1/2(4)(7)
Simplifying: Area = 2(7), Area = 14.
The area of the triangle is 14 meters squared.
Let me know if this helps!
What is the value of Q?
Answer:
52 degrees
Step-by-step explanation:
15. Two angles are supplementary. One
angle is 8 times larger than the other.
Find the measure of the two angles.
Answer:
82 and 98 degrees.
Step-by-step
Supplementary angles are equal to 180 degrees. Let's assume both are 90 degrees for both angles. You would then do the following:
90-8= (for angle 1)
90+8= (for angle 2)
Getting 82 and 98 degrees.

The ratio of yellow sweets to purple sweets is 5:4.
Alice eats 3 purple sweets and the ratio is now 5:3.
Work out how many sweets there were at the beginning.
Answer:
27
Step-by-step explanation:
The ratio of yellow : purple = 5 : 4 = 5x : 4x ( x is a multiplier )
After Alice eats 3 purple sweets, then ratio is
5 : 3 = 5x : 4x - 3
Express the ratio in fractional form, that is
[tex]\frac{5}{3}[/tex] = [tex]\frac{5x}{4x-3}[/tex] ( cross- multiply )
5(4x - 3) = 15x
20x - 15 = 15x ( subtract 15x from both sides )
5x - 15 = 0 ( add 15 to both sides )
5x = 15 ( divide both sides by 5 )
x = 3
Then
number of sweets at beginning = 5x + 4x = 9x = 9(3) = 27

bus driver drove from Philadelphia to Washington D.C. He drove the first 100 km in 2 hours, the next 55 km in 1 hour, and the final 75 km in 2 hours. What is the average speed of the bus throughout the trip?
Answer: I think it’s 46
Step-by-step explanation: Because you add up the miles he drove them divide them by how long he drove
Ex 55+75+100=230 then you divide that by 5 hours = 46 per hour
