Calculate the area l*w or s*s
Divide the two areas to get the number of 1*1 from 1 plywood then multiply by their number which is 6 here
4*8=32/1=32*6=192
There are 12 inches in a foot in april mrs Harris used 32 feet of ribbon for an art club in may she used 45 feet of ribbon how many more inches of ribbon did mrs Harris use in may than April
Answer: 156 inches
Step-by-step explanation:
12 inches = 1 foot
In April, Ms Harris used 32 feet of ribbon for an art club. We will convert this to inches. This will b e:
= 32 × 12
= 384 inches
In May, she used 45 feet of ribbon . We convert to inches.
= 45 × 12
= 540 inches
We now calculate the difference in inches. This will be:
= 540 - 384 inches
= 156 inches

2x to the power of negative 1, multiplied by 4x squared equals
Answer:
=-8x^3
Step-by-step explanation:
=2x^-1×4x^2
=-2x×4x^2
=-8x^3
(2x)⁻¹ × (4x)² = 8x
2x to the power of negative 1 is represented as follows
(2x)⁻¹The value((2x)⁻¹) multiplied by 4x squared is represented as follows
(2x)⁻¹ × (4x)²Therefore,
(2x)⁻¹ × (4x)² = (2x)⁻¹ × 16x²
(2x)⁻¹ × 16x² = [tex]\frac{1}{2x}[/tex] × 16x²

Step-by-step explanation:
Carrie has 0.125 more than Larry, Larry has 3/4 more than Harry. In total they have 151. How much does Harry have
Harry has 49.792 units.
Firstly we need to translate sentences into mathematical expressions and then we proceed to solve the resulting system of linear equations:
1) Carrie has 0.125 more than Larry:
[tex]y = x + 0.125[/tex] (1)
2) Larry has 0.75 more than Harry:
[tex]x = z + 0.75[/tex] (2)
3) In total, they have 151:
[tex]x + y + z = 151[/tex] (3)
Then, we proceed to solve the system of equations by direct substitution and clearing the remaining variable:
[tex]x + (x + 0.125) + (x-0.75) = 151[/tex]
[tex]3\cdot x -0.625 = 151[/tex]
[tex]3\cdot x = 151.625[/tex]
[tex]x = 50.542[/tex]
And the remaining solutions are, respectively:
[tex]y = 50.667[/tex], [tex]z = 49.792[/tex]
Harry has 49.792 units.

B) 12 + 4y = -44
Answer: y=-x+5 and y=-14 [tex]2x+2y=10 subtract 2x from both sides\\2x+2y-2x=10-2x \\2y=10-2x divide both sides by 2\\y=5-x rewriting using the commutative property\\y=-x+5[/tex]

If triangle DEF is an isosceles triangle with DE is congruent to EF, find x and the measure of each side
Step-by-step explanation:
Given that,
DE = 8x - 13
EF = 5x + 17
DF = x + 21
Also,
DE = EF
which means that,
8x - 13 = 5x + 17
8x - 5x = 17 + 13
3x = 30
x = 30/3
x = 10
Now,
DE = 8x - 13 = 8×10 - 13 = 80 - 13 = 67cm
EF = 5x + 17 = 5×10 + 17 = 50 + 17 = 67cm
DF = x + 21 = 10 + 21 = 31cm
