the rational number when added to 1/5 is 0.4 i think i'm not 100% sure
(I)
Given equation is x²-8x = -16
⇛ x²-8x+16 = 0
⇛ x²-4x-4x+16 = 0
⇛ x(x-4)-4(x-4) = 0
⇛ (x-4)(x-4) = 0
⇛ x-4 = 0 or x-4 = 0
⇛ x = 4 or x = 4
(ii)
Given equation is x²+2x+1 = 0
⇛ x²+x+x+1 = 0
⇛ x(x+1)+1(x+1) = 0
⇛ (x+1)(x+1) = 0
⇛ x+1 = 0 or x+1 = 0
⇛ x = -1 or x = -1
(iii)
Given equation is 4x²-24x-36 = 0
⇛ 4(x²-6x-9) = 0
⇛ x²-6x-9 = 0
⇛ x²-2(x)(3) = 9
On adding 3² both sides then
⇛ x²-2(3)x)+3² = 9+9
⇛ (x-3)² = 18
⇛ (x-3) = ±√18
⇛ x-3 = ±√(2×9)
⇛ x-3 = ±3√2
⇛ x = 3±3√2
⇛ x = 3+3√2 or 3-3√2
The second choice. Intersects means cuts the y axis. And if you go to -infinity (figuratively speaking! lol) x^3 dominates and goes to -infinity, way down, the other way for infinity
Answer:
d) 3 feet by 4 feet
Step-by-step explanation:
Volume of the prism = 48 feet³
Height if the prism = 4 feet
To determine the possible values of the length and width of the prism let's divide the volume by the height.
So 48/4 = 12
So we'll be looking for a product of two numbers to give us 12
And it's between 12 and 1, 4 and 3 , and 6 and 2.
We have only 4 and 3 in the option.
