Answer:
x = {-5, 4}.
Step-by-step explanation:
2x^2 + 2x - 4 = 36
2(x^2 + x - 2 = 18)
x^2 + x - 2 - 18 = 0
x^2 + x - 20 = 0
(x + 5)(x - 4) = 0
x = -5, 4.

Answers
The correct question is:
[tex]\angle QPS=88[/tex]
[tex]\angle RPS=5x+34[/tex]
[tex]\angle QPR=8x+15[/tex].
Find ∠QPR.
Answer:
[tex]\angle QPR = 39[/tex]
Step-by-step explanation:
From the attached figure:
[tex]QPS = QPR + RPS[/tex]
This gives:
[tex]88 = 8x + 15 + 5x + 34[/tex]
Collect like terms
[tex]88 - 15 - 34 = 8x + 5x[/tex]
[tex]39 = 13x[/tex]
Divide both sides by 13
[tex]3 = x[/tex]
[tex]x =3[/tex]
Substitute [tex]x =3[/tex] in [tex]\angle QPR=8x+15[/tex]
[tex]\angle QPR = 8 * 3 + 15[/tex]
[tex]\angle QPR = 24 + 15[/tex]
[tex]\angle QPR = 39[/tex]

D Melissa takes the 10 30 from Christchurch. How long does she wait in Wellington? Hour minutes
Answers
Answer:
1:45 hours
Step-by-step explanation:
Given
See attachment for missing part of the question
Required
How long she waits in Wellington
From the question:
She takes the 10 30 from Christchurch
So:
[tex]Christchurch\ Depart = 10\ 30[/tex]
This implies that:
She has to wait until Wellington arrives at 11 15
So:
[tex]Wellington\ Arrives= 11\ 15[/tex]
So, the wait time is:
[tex]Wait\ time = Wellington\ Arrives - Christchurch\ depart[/tex]
[tex]Wait\ time = 11: 15 - 10: 30[/tex]
[tex]Wait\ time = 1:45\ hr[/tex]

since -15/16 is a negative number, we can add both sides by 15/16 or subtract both sides by -15/16. Either way works.
p = 1/8 + 15/16
Use common denominator, which is 16:
p = 1(2)/8(2) + 15/16
p = 2/16 + 15/16
p = 17/16
17/16 is an improper fraction. If you want to use a mixed number for your answer, then:
17/16 becomes 1 1/16 (one and one-sixteenth, with 1 being a whole number and 1/16 being a fraction)

y = 2x - 2
Step-by-step explanation:
Points on graph: (4,6) and (2, 2)
Slope:
m=(y2-y1)/(x2-x1)
m=(2-6)/(2-4)
m=(-4)/(-2)
m = 2
Slope-intercept:
y - y1 = m(x - x1)
y - 6 = 2(x - 4)
y - 6 = 2x - 8
y = 2x - 2

She pays a total of $2.95 for the eggs.
She buys 6 bags of apples that each cost the same amount.
Write and solve an equation which can be used to determine xx, how much each bag of apples costs.
Answers
Answer:
6.9
Step-by-step explanation:
The total payment was 44.35 and Ella bought 6 bags of apples and eggs
eggs cost 2.95 so apples cost 44.35-2.95=41.4
lets call bags "x"
so
6x=41.4 (price)
divide both by 6
x=6.9

A jeweler has several boxes of earrings to ship to a store. Each box is a cube with a side length of 5 centimeters. The jeweler packs the boxes in a shipping container. The filled container has 4 layers, where each layer contains 7 rows and 10 columns of boxes. What is the volume of the shipping container?
Answers
Answer: [tex]35,000\ cm^3[/tex]
Step-by-step explanation:
Given
The earring box has a volume of [tex]a=5\ cm[/tex]
It is packed and loaded in the container which has 4 layers and each layer has 7 rows and 10 columns
We can say that each layer can hold [tex]7\times 10=70\ \text{boxes}[/tex]
The volume of each earring box is
[tex]V_o=a^3=5^3\\V_o=125\ cm^3[/tex]
Four layers can hold [tex]4\times 70=280\ \text{boxes}[/tex]
the container can hold 280 boxes
[tex]\therefore \text{Volume of container is}\ V=280V_o\\\Rightarrow V=280\times 125=35000\ cm^3[/tex]
