Answer:
13). -2x³ + x² + 1 14). x + 10y - 10z 15). -2x³ + x² + 1
Step-by-step explanation:
13). (x³ - x² + 4) - (3x³ - 2x² + 3)
= x³ - x² + 4 - 3x³ + 2x² - 3
= x³ - 3x³ - x² + 2x² - 3 + 4
= -2x³ + x² + 1
14). (3x + 4y - 3z) - (2x - 6y + 7z)
= 3x + 4y - 3z - 2x + 6y - 7z
= 3x - 2x + 4y + 6y - 3x - 7z
= x + 10y - 10z
15). (x³ - x² + 4) - (3x³ - 2x² + 3)
= x³ - x² + 4 - 3x³ + 2x² - 3
= x³ - 3x³ - x² + 2x² + 4 - 3
= -2x³ + x² + 1

Answer:
y = 8
Step-by-step explanation:
(y - 2) × 5 = 30
(y - 2) × 5 ÷ 5 = 30 ÷ 5
y - 2 = 6
y - 2 + 2 = 6 + 2
y = 8

Maxine can swim 240 meters in 4 minutes. What is Maxine's unit rate?
Answers
B) 4.5 minutes.
Step-by-step explanation:
A) Maxine can mow one lawn in 24 minutes, so the rate of work is:
1/24 of the lawn per minute.
Sammie can mow one lanw in 36 minutes, so the rate of work is:
1/36 of the lawn per minute.
The amount of the lawn that each has left to lawn by the minute x is:
Maxine = 1 -(1/24)*x
Sammie = 1 - (1/36)*x
we want to find the value of x such that:
2*(1 - (1/24)*x) = 1 - *(1/36)*x
which means that the amount that Sammie has left is two times the amount that Maxine has left to mow.
2 - (1/12)*x = 1 - (1/36)*x
2 - 1 = (1/12 - 1/36)*x
1/0.055 = x = 18.2
by the minute 18.2
B) Similar to before, here the rates are:
For Maxine, R = 1/6
For Sammie, R = 1/9
The amount they have left to mow by minute x is:
Maxine = 1 - (1/6)*x
Sammie = 1 - (1/9)*x
We want to solve, similar to before.
2( 1 - (1/6)*x) = 1 - (1/9)*x
2 - (1/3)*x = 1 - (1/9)*x
2 - 1 = (1/3 - 1/9)*x
1 = (2/9)*x
1*9/2 = x = 4.5
So here the solution is 4.5 minutes. Hope this helps

True or False? Will these lengths form a triangle?
Answers
Answer:
False.
Step-by-step explanation:
Since The angle sum property of traingke is 180°.
Answer:
No, these lengths will not form a triangle.
Step-by-step explanation:
The Triangle Inequality Theorem states that the sum of two sides must always be greater than the third side.
55 + 76 = 131
131 is not greater than 112.
Therefore, these lengths will not form a triangle.

BC=48 degrees, AD= ??
Step-by-step explanation:
I'm going to find the angle BC so a full circle is 360 degrees but half of a circle is 180 degrees since we are dealing with half a circle its 180, 90 and 42 are already used so lets add these two numbers which is 132 lastly to find out the remaining which is angle BC we have to subtract 180-132 which is 48. So your first answer is 48.
Next is AD which i don't know how to do, Sorry :(

Step-by-step explanation:
Tangents to a circle from an external point are congruent , then
PQ = 27.4
QR = 5.9 + 12.2 = 18.1
PR = 12.2 + (27.4 - 5.9 ) = 12.2 + 21.5 = 33.7
Then
perimeter = PQ + QR + PR = 27.4 + 18.1 + 33.7 = 79.2

KP is a radius of the circle. Is JK tangent to the circle? Note the figure may not be drawn to scale.
Answers
Answer:
JK is NOT tangent to the circle
Step-by-step explanation:
A tangent of a circle is a line that intersects a circle at one and only one point. For this reason, the radius will always intersect a tangent at a 90 degree angle to prove this single point intersection. From the triangle, we can introduce the Pythagorean theorem to see if the triangle is a right triangle:
a^2 + b^2 = c^2
48^2 + 14^2 = 36^2
2304 + 196 = 1296
2500 ≠ 1296
As this is not equal, the triangle is not a right triangle and therefore states that the tangent line does not intersect the radius at 90 degrees, meaning that it does not satisfy the requirements of a tangent line.

Simplify c: 4x+7=4x+7 ~ This clearly is a correct statement, this it is c
Simplify d: 6x-1=4x+1 ~ By subtracting 4x on each side, then adding 1 on both sides, we get 2x=2, so x can be 2.

PQR is an isosceles triangle with vertex angle Q, PQ = 5x - 24, QR = 3x - 2, and PR = 5x - 8.The length of each leg of △PQR is
Answers
Answer:
PQ = 31
QR = 31
PR = 47
Step-by-step explanation:
From the question, we have the vertex as Q
This means that we have the legs as PQ and QR; with PR as the base
The base angles of an isosceles triangle are equal and that means that the leg length values are equal
So, QR = PQ
Thus;
3x-2 = 5x-24
5x-3x = 24-2
2x = 22
x = 22/2
x = 11
So we have PQ as;
5(11) - 24 = 55-24 = 31
QR = 3(11) -2 = 33-2 = 31
PR = 5x-8 = 5(11)-8 = 55-8 = 47
