Answer:
Rectangle.
Step-by-step explanation:
If the diagonals are equal then the parallelogram is a rectangle. They are also equal in length in a square, which can be regarded as a special type of rectangle - but in this case the diagonals are perpendicular. They are also perpendicular in a rhombus.

Jason made the following calculations. Explain the errors Jason made. Give the correct answers.
a. 1/3 + 3/5 = 4/8
b. 11/12 - 5/6 = 6/6 = 1
Answer:
a. 14/15
b. 1/12
Step-by-step explanation:
a) 1/3 + 3/5
so find the lowest common multiple for the denominators which is 15
then say 15 ÷ 3 = 5
then 15 ÷ 4 = 3 (you are dividing by the denominators)
say 5 × 1 (multiple by the numerators now)
= 5
= 5/15
now say 3 × 3 = 9
= 9/ 15
now it's 5/15 + 9/15
= 14/15
Jason made an error that he just added the denominators without applying any formula.
b. 11/12 - 5/6
find the lcm
= 12
11/ 12 × 1/1 = 11/12
5/6 × 2/2 = 10/12
11-10
= 1
= 1/12
Jason made a mistake that he said 12-6 instead of finding the LCD them multiplying that fractions
The errors Jason made that he did not take LCM of denominators.
What are denominators?In math, a denominator can be defined as the bottom number in a fraction that shows the number of equal parts an item is divided into.
Given are some calculations done by Jason,
We know that, to add two fractions, we take LCM of denominators and then divide the numerator by LCM and the add,
a) 1/3 + 3/5 = 4/8
Here, Jason have not taken LCM of denominators
Correction =
[tex]\frac{15(\frac{1}{3} )+15(\frac{3}{5}) }{15} \\= \frac{5+9}{15} \\=\frac{14}{15}[/tex]
b) 11/12 - 5/6 = 6/6 = 1
Again, the error is the same.
LCM(6, 12) = 12
Correction =
[tex]\frac{12(\frac{11}{12})+12(\frac{5}{6)} }{12} \\= \frac{11-10}{12} \\= \frac{1}{12}[/tex]

Which of the following are solutions to the equation below? Check all that apply. 4x2 - 12x + 9 = 5
Step-by-step explanation:
4x² - 12x + 9 = 5 → 4x² - 12x + 4 = 0 → x² - 3x + 1 = 0
∆ = b² - 4ac → ∆ = (-3)² -4(1)(1) = 9 - 4 = 5
x = (-(-3) ± √5)/2(1) = (3 ± √5)/2
x² - 3x + 1 = 0 → (x - 3/2)² - 9/4 + 1 = 0 → (x - 3/2)² = 5/4 → x - 3/2 = ±√5 / 2 → x = ½( 3 ± √5)

The calories I burn walking can be modeled by the function y = 5x + 100,
with x representing the number of minutes spent walking. How many
calories would I burn if I walked for 75
minutes?
Answer:
X=75
Y=5X+100
Y=5*75+100
Y=375+100
Y=475
Therefore, you burnt 475 calories if you walked for 75 minutes

the first two terms of an arithmetic sequences are 7 and 3.
1.1.1 determine the eighteen term.
1.1.2 which term of the sequences Will be equal to -157?
Answer:
1.1.1) -61
1.1.2) Term 42
Step-by-step explanation:
Tn= dn (difference) + t0 (term 0)
Tn= -4n+ 11
You can now take this general rule to find out the other terms.
Tn= -4(18)+11
Tn= -61
And the term -157
Tn= -4n+11
-157= -4n + 11
-157 - 11= - 4n
-168= -4n
-168/-4= n
42= n
