Answer:
y=11
x=-4
Step-by-step explanation:
y =-x+7
2x-5y=-7
insert the first equation into the second like so...
2x+5x-35=-7
Now rearrange...
2x+5x=-7+35
Now solve...
7x=-28
x=-4
Now incert x in any equation...
y=4+7
y=11
Answer: No it is not a right triangle. It is an obtuse scalene triangle.
The measure of the angles shown is 90 degrees
<h3>Lines and angles</h3>
A line is defined as the shortest distance between two points while the point where two lines meet is known as an angle.
From the given diagram, the sum of both adjacent angles is supplementary to have:
x + 96 + 96 + x = 180
2x + 192 = 180
2x = 180 - 192
2x = -12
x = -6
Substitute the value of x into the expression
<d = x + 96
<d = -6 +96
<d = 90 degrees
Hence the measure of the angles shown is 90 degrees

Answer:
100392
Step-by-step explanation:
The expression after factorisation is 4w⁴x² (7y⁷ + 3w⁵x⁶)
<h3>What is an Expression ?</h3>
An expression is defined as a mathematical statement consisting of variables , constants and mathematical operators.
The expression given is
28w⁴x²y⁷+12w⁹x⁸
Factors of the given expression will be the common terms in both the terms
w⁴x² is common in the variable term
The HCF of 28 and 12 is 4
4w⁴x² (7y⁷ + 3w⁵x⁶)
The expression after factorisation is 4w⁴x² (7y⁷ + 3w⁵x⁶)
