Answer:

True

Step-by-step explanation:

Examples

Perfect square trinomials:- x^2 + 4x + 4 = (x + 2)(x + 2) = (x + 2)^2

A school gym has an area of 4,641 square feet and a perimeter of 284 feet. What are the dimensions of the gym?
abruzzese [7]

Answer:

dimensions are 51x91

Step-by-step explanation:

Assuming that the gym is rectangular in shape, then...

l*w=4641

and 2l+2w=284

We have two variables and two equations so to solve this we plug one equation into another.

Solve for one variable:

l*w=4641

w=4641/l

Plug into the other equation...

2l+2(4641/l)=284

Solve

l*(2l+9282/l)=284

2l^2+9282=284l

2l^2-284l+9282=0

Factor the trinomial:

2(l−51)(l−91)=0

l−51=0 or l−91=0(Set factors equal to 0)

l=51 or l=91

now, lets plug it into one of the equations to find w

51*w=4641

w=91, l=51

or...

91*w=4641

w=51, l=91

How would i find the measurement of angle 1 & 2
tatyana61 [14]

Check the picture below.

keeping in mind that a circle has a total of 360°, if the twin angles of 72°  add up to 144°, what remains for the other twin angles is 360° - 144° = 216°, and that 216 is split between both twins for 108 a piece, taking away the 40° next to ∡2, gives us ∡2.

Ber [7]

Answer:

A = 81

Step-by-step explanation:

When there is a number above the other. You will need to multiply it.

There is   a 4 so its 4 times.

-3 x -3 = 9

9 x -3 = -27

-27 x -3 = 81

When you multiply a negative number by a negative number it will be a positive.

If you multiply a positive number by a negative it will be negative.
