Answer:
well what's the question
Step-by-step explanation:
Answer:The answer is 25 units.
Step-by-step explanation:
here, ∡ABC=∡ACB
so, the given triangle is an isosceles triangle.
this means side AB and side AC are equal
so, you can write 4x+4=6x-14
solving this equation, we get x=9
finally, BC=2x+7=2*9+7=25
Say the base length is 8, and the height is 8. If you multiply it by 1/4, the new base length is 2. The formula for the area of a triangle is: A=1/2bh you take 1/2 of 2, which is 1, and you multiply by the height (8) to get 8 square units for the area. This is opposed to if you simply did the formula without multiplying by 1/4. If you avoided multiplying by 1/4, you would get A=(4)(8), which would get you 32 square inches for the area. So, in conclusion, multiplying the base by 1/4, gets you 1/4 the area.

Answer:
no; √4 = 2
Step-by-step explanation:
If an integer is the square of another integer, its square root is rational. For example, 9 = 3², so √9 = 3, a rational number.
The square root of an integer is irrational if and only if the integer is not a perfect square.
Answer: C, a set of coords is only a function if it passes the vertical line test
Step-by-step explanation:
This is essentially the vertical line test. No two sets can have the same x value because it will fail the vertical line test. In answer a, -4 correlates to two y values. It fails the line test
B easily fails the test just by visually looking at it. It fails the line test
C has different x values so this looks promising. It passes the line test
D has the number 5 correlating with multiple y values. It fails the line test
