Evaluate
1. Given that a= -2, b = 1 and c= 2
then Find
a). a²+b²+c²
b). 5/3 a²b + ¾ abc + 5
2. If x = -1, y=2 and z=-2 , evaluate
3x²y +5xy²+2xyz
Answer:
1. Ans;a). a²+b²+c² —> (-2)²+ (1)²+(2)²=4+1+4= 9b).[tex] \frac{5}{3} {a}^{2} b + \frac{3}{4} abc + 5 \\ \\ \frac{5}{3} ( { - 2)}^{2} (1) + \frac{3}{4} ( - 2)(1)(2) \\ \\ \frac{5}{3} (4) + \frac{3}{4} ( - 4) \\ \\ = \frac{20}{3} - 3 \\ \frac{20 - 9}{3} = \frac{11}{3} = 3.666[/tex]
2. Ans;3x²y+5xy²+2xyz = 3(-1)²(2) + 5(-1)(2)² + 2(-1)(2)(-2) = 3(1)(2) + 5(-1)(4) + 2(4) = 6 – 20 + 8 = – 6

5+9(1+4n)=-30
6(3-8c)=-31
-21=8+9(f-3)
9k-7-5=-25
8(3y-6)=-25
16=-5(2b-7)
Answer:
n = -11 / 9c = 49 / 48f = -2 / 9k = -13 / 9y = 23 / 24b = 19 / 10Step-by-step explanation:
1. 5+9(1+4n)=-30
-5 -5
--------------------
9 (1 + 4n) = -35
/9 /9
----------------------
(1 + 4n) = -35/9
1 + 4n = -35/9
-1 -1
------------------------
4n = -44/9
/4 /4
-----------------------
n = -11/9
2. 6(3-8c)=-31
/6 /6
---------------------
(3 - 8c) = -31/6
3 - 8c = -31/6
-3 -3
---------------------
-8c = -49/6
/-8 /-8
-----------------------
c = 49/48
3. -21=8+9(f-3)
8 + 9 (f - 3) = -21 we switched sides here
-8 -8
------------------------
9 (f - 3) = - 29
/9 /9
-------------------------
f - 3 = -29/9
+3 +3
--------------------------
f = -2/9
4. 9k-7-5=-25
9k - 12 = -25
+12 +12
--------------------
9k = -13
/9 /9
--------------------
k = -13/9
5. 8(3y-6)=-25
/8 /8
------------------------
(3y-6) = -25/8
3y - 6 = -25/8
+6 +6
-----------------------
3y = 23/8
/3 /3
-----------------------
y = 23/24
6. 16=-5(2b-7)
-5(2b-7) = 16 we switched sides here
/-5 /-5
--------------------
(2b-7) = -16/5
2b - 7 = -16/5
+7 +7
--------------------
2b = 19/5
/2 /2
---------------------
b = 19/10

A little confused on this
Answer:
Step-by-step explanation:
Let the points scores by Denny = x
Point score by Keshawn = 3 * x = 3x
Total score = 280
x + 3x = 280
4x = 280 {Divide both sides by 4}
4x/4 = 280/4
x = 70
3x = 3*70 = 210
Point scored by Keshawn = 210
If Denny's point total is 70, Keshawn's point is 210

Rewrite in the simplest terms: 8k - 9(4k +4)
8k - 9(4k + 4) = 8k - 36k - 36 = -28k - 36
Let's rewrite in the simplest term,
→ 8k - 9(4k + 4)
→ 8k - 36k - 36
→ [-28k - 36]
The simplest term is -28k - 36.
Natan turned on the stove but then forgot he was going to cook until it had been on for half an hour. How much will his forgetfulness cost on his electric bill if his stove uses 1.2 kW of electricity at the setting he used, and his utility charges him $0.18 per kW*h (kilowatt*hour) used?'
Using proportions, it is found that his forgetfulness cost him $0.108.
--------------
He used 1.2 kW for half an hour.The utility charges $0.18 per kW*h (kilowatt*hour), thus, 0.18/2 = $0.09 per kilowatt every half hour.1.2 kW used, costing $0.09 per kW. Thus:[tex]T = 1.2 \times 0.09 = 0.108[/tex]
His forgetfulness cost him $0.108.
