y = x^3 + 5x^2 + 3x x= -3
Answer:
9
Step-by-step explanation:
-3^3 +5*(3)^2 +3*-3
-27+5*9+(-9)
-27+45-9
=9
Answer:
Step-by-step explanation:
Wherever you see an x, put in -3
y=(-3)^3 + 5(-3)^2 + 3(-3)
y = - 27 + 5 * 9 + -9
y = -27 + 45 - 9
y = 9
A company installs a rectangular septic tank 30 ft long by 15 ft wide and 2 ft deep. Calculate the capacity of the tank in gallons. (Use 1ft3 = 7.48 gal.)
Answer:

You can buy 12 cookies for $4. What is the unit rate for the cost of each cookie?
Answer:
$0.33 per cookie
Step-by-step explanation:
The unit rate (cost per cookie) is
$4
---------------- = $0.33 per cookie
12 cookies
Answer:
Roughly $0.34
Step-by-step explanation:
Set up an equation:
Variable x = cost of one cookie
12cookies/$4 = 1cookie/x
12/4 = 1/x
Cross multiply
12 × x = 4 × 1
12x = 4
Divide both sides by 12
12x ÷ 12 = 4 ÷ 12
1x = 4/12
x = 0.333333
x = is about $0.34

[tex]\large\boxed{A = 12.5 \text{ units}^{2}}[/tex]
Find the area of the shape using the formula for the area of a trapezoid:
A = 1/2(b1 + b2) · h
Where:
b1 = base 1
b2 = base 2
h = height
A = area
Plug in the given bases and height:
A = 1/2(7.5 + 2.5) · 2.5
Simplify:
A = 1/2(10) · 2.5
A = 5 · 2.5
A = 12.5 units²

Step-by-step explanation:
The perimeter of a rectangle is 20 feet. The width is 4 feet less than the length. Find the dimensions of the rectangle. Then find its area.
Answer:
length = 7 ft
width = 3 ft
area = 21 sq ft
Step-by-step explanation:
let l = length
let l - 4 = width
2l + 2(l - 4) = 20
2l + 2l - 8 = 20
4l = 28
l = 7
w = 3
Area: 7 x 3 = 21
Surface are of prisms
Answer:
Area of cube formula - A=6a2
Area of rectangular prism - A=2(wl+hl+hw)
Answer:
1. Nets
2. Surface Area
3.area
4. add
5. A= 1/2 bh
Step-by-step explanation:
Side A- 8x5 = 40 sq.m
Side B - 3x8 = 24 sq.m
side c - 5x8 = 49 sq.m
side d - 1/2 ( 3x 2) = 3
side E- 1/2 (3x2) = 3
Area of rectangular prism - 2 (wl + wh + lh)
surface area of cube = 6a^2 ( a is edge)

(will mark brainliest))
Answer:
x=15
Step-by-step explanation:
Hello there!
The shown angles are vertical angles
if you didn't know vertical angles are congruent
That being said we can create equation
5x + 40 = 115
now we solve for x
step 1 subtract 40 from each side
40 - 40 cancels out
115 - 45 = 75
now we have 75 = 5x
step 2 divide each side by 5
5x/5=x
75/5=15
we're left with x = 15
