2n^2+3n=-54
a) {4,-9}
b) {6,-2}
c) {9,-3}
d) {-4 1/2, 6}
Answer:
Step-by-step explanation:
Rewrite this quadratic equation in standard form: 2n^2 + 3n + 54 = 0. Identify the coefficients of the n terms: they are 2, 3, 54.
Find the discriminant b^2 - 4ac: It is 3^2 - 4(2)(54), or -423. The negative sign tells us that this quadratic has two unequal, complex roots, which are:
-(3) ± i√423 -3 ± i√423
n = ------------------- = ------------------

Answer:
Lisa's new area will be 3600 ft ^ 2
It will be 9 times the original
Dan should increase the length by 5 times
Step-by-step explanation:
Original length = 40
New length = 40 x 3 = 120
Original length = 10
New length = 10 x 3 = 30
120 x 30 = 3600 ft^2
3600/400 = 9
It will be 9 times larger
For Dan:
ex:
length = 1
width = 2
Area = 2
He wants it to be 20 times 2
Lisa says increase 4 times
2 x 4 = 8
2 x 20 = 40
40/8 = 5

Which equation represents the linear relationship between x and y that is shown in the
table below?
Answer:
y= 5-x
Step-by-step explanation:
We notice that when we put 5 for x we get 0 which means that we must be subtracting the given x value by constant
y= 5-x makes sense, try plugging in any x value given in table and you will get its y counterpart back.
For eg, when x= -1
y= 5- (-1) = 6 (negatives add)
What is the distance between two points(0,0)(-3,5)
Step-by-step explanation:
Think of it like a right triangle. Do you have a graph handy?
Ok, graph both of the points. Now connect the points. That's our hypotenuse and the side length we want to find.
Now, bring down a line from (-3,5) to the x axis. Do you see a right triangle?
All we have to do is find the hypotenuse of this right triangle we just drew. We already have the leg lengths which are 3 and 5. Using this, do the pythagorean theorem.
9+25=34
√34 is our hypotenuse & distance between the points

Answer:
The height of the square pyramid is 24 unit.Step-by-step explanation:
Given that:
Edge of the square pyramid = 14 unit Slant height of the square pyramid = 25 unitTo Find:
The height of the square pyramid.We know that:
In pythagoras theorem.
H² = P² + B²Where,
H = Hypotenuse = 25 unitP = Height = Let xB = Base = 14/2 = 7 unitFinding the height of the square pyramid:
⇒ H² = P² + B²
⇒ (25)² = x² + (7)²
⇒ 625 = x² + 49
⇒ x² = 625 - 49
⇒ x² = 576
⇒ x = √576
⇒ x = 24
Hence,
The height of the square pyramid = 24 unitchoose two ecspresstion that are eqilivent to 5 (3a+4b)

what's the factor of 18 and the sum of -9?
Answer:
Do you really mean by -9 or cause I'm just confused but if you meant by 19 then this could help. I had my mom do whatever she could put as the answer so yeah
Step-by-step explanation:
a*b=18 ____[1]
a+b=19____[2]
[2] a=19-b ___[3]
put [3] in [1]
(19-b)*b = 18
19b-b^2 = 18
b^2-19b+18 = 0
(b-18)(b-1) = 0
so b=18 or b=1
if b=18 then a=19-18=1
if b=1 then a=19-1=18
SO two factors are 1 and 18

4) A zoologist was checking the weights of three gorillas. Gorilla A weighed 559 pounds, gorilla B weighed 827 pounds and gorilla C weighed 130 pounds. What is the combined weight of all three gorillas?
Answer:
1,516 pounds
Step-by-step explanation:
Gorilla A weighed = 559 pounds Gorilla B weighed = 827 pounds Gorilla C weighed = 130 pounds
Total weight of the gorillas = gorilla A + gorilla B + gorilla C
= 559 pounds + 827 pounds + 130 pounds
= 1,516 pounds

D. The surface area of the model is 730 square mm.
G. If one of the largest faces is not included in the model, the surface area will be 530 square mm.
The statement B, D,and G is correct for the surface area of the model.
We have given that,
The net represents a model of a storage container for sewing needles.
We have to determine which statements about the net are true.
What is the surface area?The surface area of a three-dimensional object is the total area of all its faces. In real-life we use the concept of surface areas of different objects.
Therefore the true statements are,
B. If the smallest two faces are not included, the surface area of the model will be 650 square mm.
D. The surface area of the model is 730 square mm.
G. If one of the largest faces is not included in the model, the surface area will be 530 square mm.

which inequality is graphed in red
Answer:
y>x-2
Step-by-step explanation:
When we see an inequality on a coordinate plane, we first treat it like a linear equation. The red inequality, or the red line, clearly has a positive slope. One can assume that this slope is 1. This line is also 2 units down, making the inequality x-2. There you have it!
Furthermore, we can tell it is the 1st choice because the line is dashed. In inequalities, the line is only dashed when the inequality contains < or >. Also, the shading is "above" the line, meaning the y must be greater than the line.

Joe and Steve went to a chocolate shop and got some fudge. The fudge cost $32 per kilogram. Joe ordered 75 grams of fudge. Steve ordered 235 grams of fudge. How much did each person pay? How much MORE did Steve pay than Joe?
Answer: Joe paid $2.4; Steve paid $7.52
Steve paid $5.12 more than Joe
Step-by-step explanation:
Cost of I Kg fudge = $32
But we know that 1 kg =1000g
That is to now say that
Cost of 1000g of fudge = $32
a)
If Joe ordered 75 grams of fudge then he paid
Now 1000g of fudge = $32
75g of fudge will cost =75 x 32 /1000 =$2.4
also .
b) 235 grams of fudge ordered by Steve will cost
235 x 32 / 1000=$7.52
Therefore, Steve paid $5.12 ($7.52-$2.4) more than Joe

Answer:

Step-by-step explanation:
find a:c and a:b:c of a:b =4:5, b:c=3;5
pls ans with explanation
Here's the solution,
a : b = 4 : 5
b : c = 3 : 5
now, we can combine the ratios if the value of b is equal in both of them, and we have to make sure it's the minimum value since we have to obtain it in the simplest form, so let's take the L.C.M of b in both proportions .
L.C.M of b in both ratios is 15
so
ratio 1.)
a : b = 4 : 5 a : b = 12 : 15( just multiplied both numbers by 3 to make b = 15 )
ratio 2.)
b : c = 3 : 5b : c = 15 : 25( just multiplied both numbers by 5 to make b = 15)
now, simply combine the equations to get,
a : b : c = 12 : 15 : 25
and hence,
a : c = 12 : 25
