=> 24
Answer:
24
Step-by-step explanation:
Use distributive property:
4(a + b) = 4a + 4b
Then substitute the values in for the variables:

∆ABC is reflected across the y-axis and translated 3 units up to create ∆XYZ. Select all statements that are true about ∆ABC and ∆XYZ.
Answers
Answer:
Step-by-step explanation:
Suppose A is (-3,6) when it starts out.
When A is reflected across the y axis, it takes on the opposite sign.-3 becomes + 3Nothing happens to the y value of the point from this transformationThe new point is X(3,6)Now we take the reflected point and move it three units. up
Up means increase the y value of the new point (X)The y value = 6Increase the y value by 3This makes 6 + 3 = 9So after all that X becomes (3,9)Answer:

Corresponding sides of ∆ABC and ∆XYZ are not congruent.

Answers
Answer:
37°
Step-by-step explanation:
(4x + 2)° = 150° [Vertically Opposite Angles]
=> 4x = 150 - 2
=> 4x = 148
[tex] = > x = \frac{148}{4} [/tex]
=> x = 37° (Ans)
Angle (4x+2)° and angle 150° are vertically opposite angles so, their measures will be equal.
Which means :
[tex] =\tt 4x + 2 = 150[/tex]
[tex] =\tt 4x = 150 - 2[/tex]
[tex] = \tt4x = 148[/tex]
[tex] =\tt x = \frac{148}{4} [/tex]
[tex]\hookrightarrow \: \color{plum}x = 37[/tex]
Let us check whether or not we have found out the correct measure of x by placing 37 in the place of x:
[tex] =\tt 4 \times 37 + 2 = 150[/tex]
[tex] = \tt148 + 2 = 150[/tex]
[tex] =\tt 150 = 150[/tex]
Since the measures of both the angles are equal we can conclude that we have found out the correct value of x.
Thus, the value of x in this figure = 37
Therefore, the correct option is (A) 37.

Jonathan is putting a border around a right triangle and needs to figure out the triangle's height. If the triangle has a base length of 4 cm and a total area of 24 cm², what is the height?
Answers
Step-by-step explanation:
formula to find area of a triangle:
A=1/2 × base × height(h)
insert the values into the formula:
24=1/2 × 4 × h
solve for h :
24=2h
24/2=h
h = 12 cm ( Ans )
The height of triangle will be 12 cm.
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
The triangle has a base length of 4 cm.
And, A total area of 24 cm².
Now,
We know that;
Area of right triangle = 1/2 × Base × Height
⇒ 24 = 1/2 × 4 × h
⇒ 24 = 2 × h
⇒ h = 24 / 2
⇒ h = 12 cm
Thus, The height of triangle = 12 cm.

A swimming pool had 30 gallons of water in it. Then water was added to the pool at a rate of 5 gallons per second. The function y= 5t + 30 describes the relationship between the number of gallons, y, and the number of seconds water was added, t. Select all of the ordered pairs that correspond to input-output pairs for the function.
A. (45,3)
B. (3,45)
C. (0,30)
D. (30,0)
Answers
The (45,3) and (30,0) are the correct-ordered pairs that correspond to input-output pairs for the function.
What is function?Each element of X receives exactly one element of Y when a function from one set to the other is used. The sets X and Y are collectively referred to as the function's domain and co-domain, respectively.
Given the function:
y = 5t +30,
Here y is the no of gallons and t is the time.
Take the values of option A and substitute in the function,
45 = 5 × 3 +30
45 = 45
Hence, it is the correct-ordered pair,
Similarly, take option b
3 = 45 × 5 +30
3 ≠ 255
Now take option c,
0 = 30 × 5 +30
0 ≠ 180
Take the last option,
30 = 0 × 5 +30
30 = 30
Hence, it is also the ordered pair.
Therefore, the (45,3) and (30,0) are the correct-ordered pairs that correspond to input-output pairs for the function.
