3(2x+2)=3x-15
mutiply the bracket by 3
(3)(2x)(3)(2)= 6x+6
6x+6= 3x-15
move 3x to the other side
sign changes from +3x to -3x
6x-3x+6= 3x-3x-15
6x-3x+6= -15
3x+6= -15
move +6 to the other side
sign changes from +6 to -6
3x+6-6= -15-6
3x= -21
divide by 3 for both sides
3x/3= -21/3
x= -7
Answer: x= -7
Answer:
y+4 = 9/4(x-3)
Step-by-step explanation:
m=slope and b=y-intercept (probably useful for later on in the school years)
y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point
Substituting in what we know
y--4 = 9/4(x-3)
y+4 = 9/4(x-3)
Answer:
TSA = 62 ft^2
The total surface area is 62 ft^2
D. 62
Complete question;
A student draws the net below to show the dimensions of a container that is shaped like a right rectangular prism. What is the total surface area?
A. 19 B. 30 C. 38 D. 62
Attached is the image.
Step-by-step explanation:
Total surface area = Length × breadth
Total surface area is equal to the sum of surface area of section 1(main), surface area of section 2(wing) and surface area of section 3(wing).
TSA = SA1 + SA2 + SA3
TSA = 5×(2+3+2+3) + 3×2 + 3×2
TSA = 50 + 6 + 6
TSA = 62 ft^2
The total surface area is 62 ft^2
