10. Solve for all values of x algebraically (find the zeroes):
3x^2 +12x – 7 = x^2+ 3x – 2
Answer:
x = -5 or 1/2
Step-by-step explanation:
From the question,
3x²+12x-7 = x²+3x-2
Collect like terms
3x²-x²+12x-3x-7+2 = 0
2x²+9x-5 = 0
Using factorization method to solve the quadratic equation
2x²+10x-x-5 = 0
(2x²+10x)-(x+5) = 0
2x(x+5)-1(x+5) = 0
(x+5)(2x-1) = 0
Either,
x+5 = 0
x = -5
or,
2x-1 = 0
2x = 1
x = 1/2.
Therefore,
x = -5 or 1/2

Answer:
16
Step-by-step explanation:
The formula used to find the area of a triangle is
[tex] \frac{1}{2} b \times h[/tex]
so the area of the triangle is
[tex] \frac{1}{2} \times 8 \times 4[/tex]
because 8 is the base and 4 is the height of the triangle
Therefore the area of the triangle is 16
What is the surface area of the box if it is scaled up by a factor of 10?
the surface area is 206 in, width 9 in, length 13 in, height 4 in
(first to answer gets brainly please need answer quick!)
Answer:
6l², where l is the length of one side.
If the side is increased 10 times,
6(10l)²
=100 x6l²
The surface area increases 100 times. Thus, the new surface area is
272 * 100
= 27,200 sq in
Step-by-step explanation:
hey i know this may be a lame question but can anyone help me how can i multiply 16 with 3,142 (with steps) ?? :/
Answer:
50272
Step-by-step explanation:
Okay how I solve these equations is I take the problem apart like this:
3142 = 3000 + 100 + 40 + 2
Now we multiply each number by 16:
3000 * 16 = 48000
100 * 16 = 1600
40 * 16 = 640
2 * 16 = 32
Then we add all the totals together:
48000 + 1600 + 640 + 32 = 50272
Hope this Helps ;)

The price of a toy usually costs £50 is increased to £65 work out the percentage increase
Answer:
Step-by-step explanation:
10% of 50 = 5
5% of 50 = 2.5
to get to 65 u do 5+5 = 10 so so far that is 20% but 20% only gets u to 60 so u add another 10% to reach 65
u have used 30% so the answer to yr question is 30%
does this help comment if / if notSolve the inequality. 3/4x−2/3≤5/6 Choose the solution that is graphed on this number line.
Answer:
x ≤ 2
(when graphed, closed circle on two, shaded to the left)
Step-by-step explanation:
3/4 x - 2/3 ≤ 5/6
Add 2/3 to both sides:
3/4x ≤ 5/6 + 2/3
3/4x ≤ 3/2
Divide by 3/4 on both sides:
x ≤ 3/2 ÷ 3/4
x ≤ 2

The scatter graph for level of water in a dam on each day and date for one month type of data is most likely to suggest a linear association.
What is scatter plot?A scatter plot, like a scatter chart or graph, employs dots to represent the values of two numerical variables. The horizontal value represents the data from individual points. Hence, it is used to observe the relationships between variables.
The scatter plot can provide the values for the data set. The points can be of various sizes, colours, and forms. The information is presented in the form of points.
The values are represented on the vertical axis. The data association can be positive, negative, or neutral. A mosaic and a fluctuational diagram can be displayed on the scatter plot.
Thus, the plot which can be linear association form level of water in a dam on each day and date for one month

eight times a number plus five times another number is -13. the sum of the two is 1. What are the numbers?
Answer:
-6 and 7
Step-by-step explanation:
x is one number and y is the other
(1)----------------- 8x+5y=-13
(2)------------------ x+y= 1
first, let multiply both sides of (x+y=-1) by 8
(3)----------------- 8x+8y=8
lets subtract (1) from (3)
(8x+8y)-(8x+5y)=8-(-13)=3y
8-(-13)=3y -> 21=3y
y=7
lets plug in 7 into (2) for x
x+7=1
x=-6
the numbers are -6 and 7

help me Find the Area of the Trapezoid
Answer:
294
Step-by-step explanation:
14 x 9 = 126
so the area of your rectangle is 126.
15 - 9 = 6
so 6 is the width, 14 is the height.
14 x 6 = 84
now you have to multiply is by 2, because there is still another Triangle on the other side.
84 x 2 = 168
Now you take 168 and 126 and add your areas, and you have found the complete area!
168 + 126 = 294

A diameter of a circle has enpoints (-2, 10) and (6, -4) in the standard (x, y) coordinate plane. What is the center of the circle?
Answer:
The center of the circle is [tex]C(x,y) = (2, 3)[/tex].
Step-by-step explanation:
The center of the circle is the midpoint of the segment between the endpoints. We can determine the location of the center by this vectorial expression:
[tex]C(x,y) = \frac{1}{2}\cdot R_{1}(x,y)+ \frac{1}{2}\cdot R_{2}(x,y)[/tex] (1)
Where:
[tex]C(x,y)[/tex] - Center.
[tex]R_{1} (x,y)[/tex], [tex]R_{2} (x,y)[/tex] - Location of the endpoints.
If we know that [tex]R_{1} (x,y) = (-2,10)[/tex] and [tex]R_{2} (x,y) = (6,-4)[/tex], then the location of the center of the circle is:
[tex]C(x,y) = \frac{1}{2}\cdot (-2,10)+\frac{1}{2}\cdot (6,-4)[/tex]
[tex]C(x,y) = (-1, 5) + (3, -2)[/tex]
[tex]C(x,y) = (2, 3)[/tex]
The center of the circle is [tex]C(x,y) = (2, 3)[/tex].

Step-by-step explanation:
6(7x + 10)
6(7x) + 6(10) Distribute
42x + 60 Simplify
Answer:
6(7x+10)
Step-by-step explanation:
Hello There!
We can find an equivalent expression by factoring
First we need to find the greatest common factor (GCF)
GFC - largest number that both numbers can be divided by
Lets write down all of the multiples of each number
42 - 42 and 1, 21 and 2, 13 and 3, 6 and 7,
60 - 60 and 1, 30 and 2, 20 and 3, 4 and 15, 6 and 10
Then we find the greatest common factor which would be 6
42x/6=7x
60/6=10
so we can conclude that an equivalent expression would be
6(7x+10)
