Answer:
24
Step-by-step explanation:
4/5 of 30 is same as 4/5 x 30
Of means multiplication
So 4x30 /5
= 120/5
= 24
Answer:
x = 5
Step-by-step explanation:
Since the triangles have to be congruent (through SSS), we know that:
2x + 3 = 4x - 7
We simplify this to: 2x = 10
And then: x = 5
Step-by-step explanation:
Length of rectangle is 140 m and its breadth is 100 m
Perimeter = sum of all sides
For rectangle, P = 2(l+b)
P = 2(140+100)
P = 480 m
Area = length × breadth
For a rectangle, A = lb
A = 140 × 100
A = 14000 m²
We need to write the length and breadth such that it has the same perimeter but a larger area.
Let the length is 110 m and breadth is 130 m.
Perimeter, P = 2(110+130)
P = 480 m
Perimeter is same as previous
Area, A = 110 × 130
A = 14300 m²
Area is more than the initial area.
Hence, this is the required solution.
Answer:
probably a. metres
Step-by-step explanation:
hectometres are huge and the other two are super small so thats my guess lol
Answer:
x = 2
Step-by-step explanation:
h(x) = f(x) + g(x) = x³ + 2x² + 1 - x³ - x² - 4x + 4 ← collect like terms, thus
h(x) = f(x) + g(x) = x² - 4x + 5
Given
h(x) = 1, then
x² - 4x + 5 = 1 ( subtract 1 from both sides )
x² - 4x + 4 = 0 ← in standard form
(x - 2)² = 0 ← in factored form ( perfect square ), thus
x - 2 = 0 ⇒ x = 2
