A rectangle has a perimeter of 54 cm. It has a length of 15 cm. What is its area? *
d1i1m1o1n [39]

the area is 180 cm. to find the perimeter you would do 15+15+14+14 to get 54 cm. So for area you do (l×w) which is 15×14=180.

Please help me!!!!!!!! Factor z2 – 3z – 18
Vladimir [108]
First, the factor pairs for 18 are:
1, 18
2, 9
3, 6

Since the middle term is -3, the two factors must be 3 apart. The only pair that is 3 values apart is 3, 6.
Since the middle value is negative, the larger number is negative. This means that the 6 is negative.
z = -6
z = 3

Set each equal to 0;
z = -6
z + 6 = 0

z = 3
z - 3 =0
So your factors are (z+6) and (z-3), or answer B.

the hypotenuse of a right angled triangle is 26cm, if the other side 24cm. find the length of the third side​
weeeeeb [17]

You need Pythagorean theorem for this.

a² + b² = c², where c is the hypotheneus and a and b are the sides of the right triangle.

24² + x² = 26²

x² = 676-576

x = ±√100

x = 10 (-10 is rejected because length of triangle cannot be a negative number)
