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

Given parallelogram ABCD, solve for x
Answer:
x=5
Step-by-step explanation:
Set your equation up as following:
6x-10=3x+5
move the 3x to the left side by substracting
3x-10=5
now add 10 to the right side
3x=15
Divide 15 by 3 to isolate x
x=15/3
x=5

solve the equation using the quadratic formula
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

Can someone help me out my grads are bad
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)

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
Total weight of the gorillas = 1,516 pounds

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 unit
