Answer:
Ok so first you want to distribute the -1 in front of the 3x^2-7x+1
Which turns the problem into
X^2+5x-6 -3x^2+7x-1
Then just combine like terms
-2x^2+12x-7
Also ^ followed by the number is the exponent

What is the area of the figure shown?
Step-by-step explanation:
[tex]3.5 \times 6 + (5 - 3.5) \times 6 \div 2 = \\ = 21 + 9 \div 2 = \\ = 25.5[/tex]
Answer:
25.5m
Step-by-step explanation:
square area: 6m*3.5m = 21m
Triangle height: 5m - 3.5m = 1.5m
Triangle area: [tex]\frac{1.5m*6m}{2}[/tex] = 4.5m
Total area: 21m + 4.5m = 25.5m
How much greater is the volume of a triangular prism with base area of 15 cm^2 and height of 3.8 cm than the volume of a triangular pyramid with the same height and base area
28.5 is the Answer i thinck i do not now i forgot how to do it in college we do not do that any more

Answer:
1. x = 180 - (90 + 57) = 180 - 147 = 33°2. given: AB = BC = ACside = equilateral (all sides are equal)
measure = acute (3 acute angles) 180/3 = 60°
3. x = 180 - (29 + 15) = 180 - 44 = 136°4. no it's not unique because we don't have any side length.5. ∠D = 2×38∠D = 76°

5 Solve for x. 8 = 2x + 4
Answer:
8 = 2x + 4collect like terms8 - 4 = 2x4 = 2xdivide both sides by 24/2 = 2x/2X = 2Answer:
x=2 (answer should have a positive sign.)Step-by-step explanation:
To solve this problem, you have to isolate the x from one side of the equation.
First, switch sides.
8=2x+4
2x+4=8
Subtract by 4 from both sides.
2x+4-4=8-4
Solve.
8-4=4
2x=4
Then, divide by 2 from both sides.
2x/2=4/2
Solve.
4/2=2
x=2
The solution is 2.

Karl needs to build a stage that has an area of 84 square feet. The length of the stage should be longer than the width. What are the possible whole number measurements for the length and width of the stage?
Complete the table with possible measurements of the stage.
Answer:
84 = L x w
84 = 84 x 1
84 = 42 x 2
84 = 28 x 3
84 = 21 x 4
84 = 14 x 6
84 = 12 x 7

What is the measure of ∠CEF?
A. 80 degrees
B. 90 degrees
C. 100 degrees
D. 110 degrees
Answer:
D. 110
Step-by-step explanation:
30+40=70
180-70=110
Answer:
∠CEF = 110°
Step-by-step explanation:
ΔBED ,
∠BED + ∠BDE + ∠DBE = 180 {Angle sum property}
∠BED + 40 + 30 = 180
∠BED + 70 = 180
∠BED = 180 -70
∠BED = 110°
∠CEF = ∠BED {Vertically opposite angles}
∠CEF = 110°
