factorise (2t-7)²-(5t-4)²
with working pls
Answer:
33+12t−21t^2
Step-by-step explanation:
(2t-7)²-(5t-4)²
Use binomial theorem (a−b)^2 = a^2−2ab+b^2 to expand (2t-7)².
4t^2−28t+49−(5t-4)²
Use binomial theorem (a−b)^2 = a^2−2ab+b^2 to expand (5t-4)².
4t^2−28t+49−(25t^2−40t+16)
To find the opposite of 25t^2
−40t+16, find the opposite of each term.
4t^2−28t+49−25t^2−40t+16
Combine 4t^2 and −25t^2 to get −21t^2.
−21t^2−28t+49+40t−16
Combine −28t and 40t to get 12t.
−21t^2+12t+49−16
Subtract 16 from 49 to get 33.
−21t^2+12t+33
Swap terms to the left side.
33+12t−21t^2

triangle similarity i think ... picture included * SIN COS TAN
Answer:
d = 105tan(37°)Step-by-step explanation:
opposite (o) = d
adjacent (a) = 105
Angle A = 90 - 53 = 37°
Therefore,
the correct equation would be
tan(A°) = opposite/adjacent
tan(37°) = d/105
d = 105tan(37°) ✅d = 105 × 0.7535540501
d ≈ 79.12 units

Hannah is putting in a tile floor. She needs to determine the angles that should be cut in the tiles to fit the corner. The angle in the corner measures 90. One piece of the tile will have a measure of 38. Write an equation, and use it to determine the measure of the unknown angle.
Answer:
equation
180=90+38+x
where x equals missing angle
x=52
Step-by-step explanation:
Hello There!
remember the sum of the interior angles of a triangle is 180
so to find the measure of the missing angle we subtract the given angles from 180
180-90-38=52
so the measure of the missing angle is 52
please help! literally desperate for help asap!

Answer:
Step-by-step explanation:
area of base = 5×11 = 55 ft²
area of triangle = ½×5×6 = 15 ft²
area of rectangular face = 6.5×11 = 71.5 ft²
surface area = 55 + 2×15 + 2×71.5 = 228 ft²

What is the equation of the line that passes through (3.-5) and is parallel to 5x - 3y = 15?
Answer:
y = 5/3x - 10
Step-by-step explanation:
[tex]5x - 3y = 15\\-3y = -5x + 15\\y = 5/3x - 5[/tex]
that means the slope of the new line also has to be 5/3 because parallel lines have the same slope.
put it in point-slope form:
y - -5 = 5/3(x - 3)
y + 5 = 5/3x - 5
y = 5/3x - 10

a brick measures
l= 15 cm
b= 8 cm
h= 5 cm
how many bricks will be used to make a wall of length=15 m, breath=10 m and height=8m
Answer:
2000000 bricks
Step-by-step explanation:
The computation of the number of bricks to be used is shown below:
The Volume of brick is
= (15 × 8 × 5)cm^3
= 600 cm^3
And, the Volume of wall is
= (1500 × 1000 × 800)cm^3
= 1200000000 cm^3
Now Bricks needed is
= 1200000000 cm^3 ÷ 600cm^3
= 2000000 bricks
