Answer:
150
Step-by-step explanation:
(8+4)^2 + (18/3)
12^2 + (18/3) First Evaluate (8+4)^2 and divide 18 by 3
144 + 6 Add
=150 <--- And 150 is your final answer :)
Side Note: When using powers it is the number times itself a certain amount of times. That is why we multiply 12 * 12.

can someone help pls
Answer:
[tex]x=5[/tex]
Step-by-step explanation:
1. Approach
The most logical steps to solve the given equation are to distribute and simplify the left side of the equation. Then use inverse operations to bring all of the terms to the left side of the equation. After doing so, one can factor the equation again, then use the zero-product property to solve it.
2. Simplify
Distribute the terms on the left side, multiply everything in the first parenthesis by everything in the second,
[tex](x+1)(x-11)=-36[/tex]
[tex](x)(x)+(1)(x)+(-11)(x)+(1)(-11)=-36[/tex]
Simplify this expression by performing the multiplication and then combining like terms,
[tex](x)(x)+(1)(x)+(-11)(x)+(1)(-11)=-36[/tex]
[tex]x^2+x-11x-11=-36[/tex]
[tex]x^2-10x-11=-36[/tex]
Inverse operations,
[tex]x^2-10x-11=-36[/tex]
[tex]x^2-10x+25=0[/tex]
3. Factor and solve,
Now that has the simplified version of the equation, one should factor it. Rewrite the quadratic expression as a product of two linear expressions,
[tex]x^2-10x+25=0[/tex]
[tex](x-5)^2=0[/tex]
Use the zero product property to solve this expression. The zero product property states that any number times zero equals zero. Since ([tex](x-5)^2[/tex]) is just ([tex]x-5[/tex]) multiplied by itself, thus, when solving, one can ignore the square part of the equation:
[tex](x-5)^2=0[/tex]
[tex]x-5=0[/tex]
Inverse operations,
[tex]x-5=0[/tex]
[tex]x=5[/tex]

Andrew bought four bottles of lemonade and two bottles of water for €2.45. From the same shop Michael
bought two bottles of lemonade and four bottles of water for €2.35. What is the total cost of one bottle of
lemonade and one bottle of water?
Answer:
0.8 euro
Step-by-step explanation:
Suppose the price of bottle of lemonade is x, when the bottle of water costs y.
Four bottles of lemonade cost 4x, two bottles of water cost 2y
4x+2y=2.45
Two bottles of lemonade cost 2x, four bottles of water cost 4y
2x+4y= 2.35
These equations( 4x+2y=2.45 and 2x+4y= 2.35) are simultaneous, so
multiply the first one by -2
-8x-4y=-4.9
-8x-4y+2x+4y= -4.9+2.35
-6x=-2.55
x=0.425 euro - the cost of bottle of lemonade
y=(2.45-4*0.425)/2
y=0.375 euro - the cost of bottle of water
0.425+0.375= 0.8 euro - the total cost of one bottle of
lemonade and one bottle of water
Answer:
price of lenonade bottle is 0.425
price of water bottle is 0.375
Step-by-step explanation:
In explaination, 'x' is the value of lemonade bottle and 'y' is the value of water bottle.
All explaination is in picture below.

Show all work to solve the equation for x. If a solution is extraneous, be sure to identify it in your final answer.
square root of the quantity x minus 3 end quantity plus 5 equals x
x=7 is the solution for the given equation
x=4 is the extraneous solution .
Given :
[tex]\sqrt{x-3} +5=x[/tex]
Explanation :
To solve the given equation for x , we need to remove the square root first
Subtract 5 on both sides
[tex]\sqrt{x-3}+5=x\\ \sqrt{x-3}=x-5\\\\[/tex]
Take square on both sides to remove square root
[tex]x-3=(x-5)^2\\x-3=x^{2} -10x+25\\[/tex]
Subtract x and add 3 on both sides
[tex]0=x^{2} -11x+28\\0=(x-7)(x-4)\\[/tex]
Set the factors =0 and solve for x
[tex]x-7 =0\\x=7\\\\\\x-4=0\\x=4[/tex]
x values are 4 and 7
Now we check the values using original equation and verify it
[tex]x=4\\\sqrt{x-3} +5=x\\\sqrt{4-3} +5=4\\\\6=4 \\[/tex]
x=4 does not satisfies the original equation
Now we check x=7
[tex]\sqrt{7-3} +5=7\\7=7[/tex]
x=7 is the solution

Answer:
DCC
Step-by-step explanation:
CDDCDC
Different type of spaghetti dinners is 8
What is combination ?
"The number of possible arrangements in a collection of items where the order does not matter."
For 4 different shaped of noodles = ⁴c₁
⁴c₁ = 4
For two kinds of cheese = ²c₁
²c₁ = 2
Now , multiplying these 4×2 = 8

Anyango divided her 50 hectares farm as follows.maize took 35% of the farm beans 32%;potatoes 24% and millet took the remaining part.
a). What is the area covered by each crop in hectares?
b) Anyango increased the plot for beans by 11 and quater % and reduced the plot for potatoes by 15%in the following year.
Answer:
a = Maize takes up 17.5 Hectares, Beans takes up 16 Hectares, and Potatoes takes up 12 hectares
b = Beans takes up 17.8 hectares, and Potatoes takes up 10.2 Hectares
Step-by-step explanation:
A: 50/100 = .5
.5 is = to 1% of the farm
Maize = .5*35
Maize = 17.5 Hectares
Beans = .5*32
Beans = 16 Hectares
Potatoes = .5*24
Potatoes = 12 hectares
B: Beans: 16*1.1125 = 17.8 hectares
Potatoes: 12*.85 = 10.2 Hectares
